“Dr. Prat-Camps' breakthrough builds on research he and colleagues have carried out over a number of years focusing on the control and manipulation of magnetic fields by the use of metamaterials.”
Metamaterials allow researchers to shrink a synchrotron onto a chip

“Now researchers report that a photonic device that relies on metamaterials can bend light and generate terahertz radiation, acting as a minuscule synchrotron on a chip.”
What are metamaterials and why do we need them?

“Back in the day before cable and satellite, TVs had metal antennas. Those antennas were designed for radio waves that were centimeters to meters in length. We are working to create nanoscale antennas that would be able to respond to visible light with wavelengths of 400 to 700 nanometers, or infrared light, where wavelengths are on the order of a micron.”

Video on invisibility
It's already up.
Didn't see it.
That's because is invisible
You wouldn't what invisibility as you will not be able to see anything. And if it is visible light that is being diverted, someone with an IR camera would be able to see you.
@@danacoleman4007 Oh yeah, I saw that video!
got excited when I heard magnetic diode
Me: *wow* , that is a step to 'free energy'[edit: almost free cause materials price, not sayn' like pulling my body with hand sense]
Video dude: can charge phone faster
d6wave
It’s funny how you mention that because the free energy device that I was trying to make actually requires a mechanism that goes only one way Similar to an electric diode.
@@d6wave there's no such a thing as free energy
Nerd! lol!
Vapor Wave - sama yes there is, not 100% free but we can gain it in ways that seem 100% free to us.. like a windmill for example.. everything is energy, look at the power that is released from cracking an atom for fucks sake
Metamaterials go beyond the properties of nature?
Sounds like Vibranium
Evariste Galois Hah, no.
What he said about the nanoscopic structure of the gold changing its colour is the same as how some butterflies have tiny repeated structure on their wings to make them look irridescent blue, but they are not blue at all. They are just only letting blue light reflect.
In fact, many meta-materials are nature inspired or directly copied. So nature IS already meta
Evariste Galois In almost Every video I view your comments are the most liked.
wrong.. a lot of animals use metamaterials properties to accomplish things..
The most common example is the blue butterfly which is not really blue.
Sounds like clickbait
Not far off... Molecular edges on metamaterials containing various energy transfer properties (like electrical conductivity)...
Would give us *plasma swords*
We're getting there people.
Iridescent metallic insect shells (like a jewel beetle or some house flys) are a great example of structure rather than chemical makeup creating the appearance and color of a surface. Also, about lenses using structure rather than lens shape: Canon actually sells lenses that use microscopic diffraction engravings in some elements to make big telephotos much lighter and smaller. Look up Canon DO (diffractive optics) lenses.
Thanks for a very clear layman's description of metamaterials. Nice work!
Love learning from you guys!!!
Getting a lot of metamaterials lately suggested. Great video with a general overview. Thinking 3D fractal antennas too now for some reason.
I will use these materials to make Wakanda
Dont you mean... "Cowdungkanda"
WAKANDA FOREVA
I'll help
No, you will drop a rap album to make cash then hire white people to make Wakanda.
He knows de wey.
dont blue butterflies use this same kind of nano structure to create the illusion of blue
they due!
Nope, 'same kind of nano structure' would imply these metamaterials are also blue. You are correct however, in that they are using nanostructures in order to make themselves appear blue, so kudos for that observation! But technically, they are entirely different nanostructures. I'm also not sure butterfly nanostructures have any use beyond just making themselves blue. I've never looked into it.
The blue color of certain butterflies results from naturally occurring photonic crystals, which can be considered as a type of metamaterial.
Blue eyes do too
This video and these materials/concepts are so cool!!
I'm a materials scientist so I need to say that the effect that electromagnetic radiation has on ALL materials is affected by their structure. Typically this is the crystal structure (well define, periodic arrangement of atoms in a solid) or, for polymers, the chemical structure. Metamaterials just add another layer of complexity on a larger scale (nano or micro scale). We call this mesoscale structure.
Merely adding another layer of complexity is a massive downplay imo. With metamaterials you can (likely) get properties of exotic materials with cheaper materials by altering their geometry. Plus this video hasn't touched mechanical metamaterials, auxetics for example.
You assume that our universe is the only one and that physics as we know it operates the same in all of them. Kind of stupid, actually.
@@johnturtle6649 ? What?
@@mcrib5794 Can you read? Do you understand the words? It's not a hard concept to comprehend.
@@johnturtle6649 context goddamn it. It's obvious that we're talking specifically on the universe we currently live in. Set the multiverse theory aside for now will you?
This is amazing cant wait to see it in everyday use
love meta materials, keep it up on this subject please!
Stunning. Thanks for the update. I imagine this sort of material can also be used to 'watermark' materials for authentication. Take diamonds vs blood diamonds. Or even currencies to thwart counterfeiting.
Julian is a very intelligent and kind person. He always wears glasses, which gives him a studious appearance. It's great to see someone who is dedicated to learning and being their best self. I hope you can take a break from thinking about meta materials and give Julian the appreciation he deserves.
lol wut
He was arrested a couple of months ago.
This is and Amazing video!
I want to see that video about invisibility soon! :D
This guy is a lot easier to listen to, and learn from, than some others.
Interesting...🤔 Thanks for the information!!
I have toured Argonne national labs in Darien Illinois before and saw the synchrotron that emits high energy x-rays. It was one of the coolest experiences I’ve ever had
Yeah, it was pretty POSSIBLE to make a complete video on this topic, but damn they need to make money on videos!
How much does the mini synchrotron scale up? Could we use it to significantly boost the power of the LHC without making it significantly bigger, for example?
Who came here to just FEEL a lil smarter?
Nope I came here because I'm bored but also I'm sick of them making so many videos about something fantastic that will amount to nothing.
Mee
me. but only felt a lil meta.
It doesn't matter if you "feel" smarter, if you didn't understand even a portion of the video... You gained nothing, and therefore just as stupid as you arrived.
you can make Terahertz radiation through yoga - the microtubules are metamaterials with the tubulin inside. No synchotron needed anymore!!
I saw the notification last night, went to sleep and wake up for this episode....so Meta…
Thank you mate! Excellent video
Very interesting! Bravo! I need to read more on this.
The channel videos are awesome! Please put subtitles in Portuguese, Brazil thanks!
Great Video, Meta Materials for the win!!
Does this mean we can make green eggs and ham now
These meta materials are amazing🔥🔥👍🏾
I thought Graphene was gonna shape the future but damn metamaterials are insane
How about bending gravity? 😏
You mean Time-space fabric ?
wabi sabi stuff with mass already does :/
Fqxre nope, your understanding of gravity is a lie
Haha i want to fucking die
Gytole gravity has nothing to do with mass, so his mother wouldn't do shit
NO WAY THIS IS SO FREAKIN COOL. I knew invisibility would come and some point in time. Being able to bend light by material structure that’s so simple too. And to think we’ve been doing it all along without even knowing(Mirrors and stuff)
We knew about mirrors, it's ok :)
Would this be applicable in micro and nano technology?
What about the process(es) by which we make these metamaterials? Is there any promise in scaling production? Discoveries like this are often too limited by expense to be applicable; at least until someone works out the engineering side of things, which is usually (but not always) speculative.
I am a final year computer science student and I am exploring the designing of metamaterials using AI.. this video was a gem,,,
can meta materials be used for building a more efficient space propulsion system? And how?
Watching this makes me feel smart.
Can you test if you can alter the surface of everyday rubber-coated wire to reflect electromagnetic waves? or at least hypothesize a theory?? thanks ;)
Need that invisibility video ASAP.
let me explain u , we can acheive metamaterial and the thing called "invisibilty" if the refractive index of a material is negative or if sini/sinr = -n(mu)
Can we use this to make an antenna that actually improves digital hdtv reception though.
*_What are you guys Seeking?!_*
KNAWLADGE
Metamaterial which btw i didnt know about ti'l now
Discomfort.
Adds for geeks
I seek the Holy Grail.
Make a video about invisibility
They already did.
How do they go about making it stable? I'd imagine the materials would fight to go back to their regular structures, no? I'm kind of clueless about all of this, but curious.
Oi! You peaked my interest in magnetic diodes for induction charging... ye honna leave me hanging like that lol. (Learning how to make a wireless charger here)
Panic The Scholar Knight. Very cool right? checkout "Radiant Power too"
So impressive. Whoever wrote this is a genius. Thank you.
How we can make meta materials?
I read somewhere that if we mix metal with some another material. But what is that another material?
PhDVlog explaining a unique design of metamaterial using three different materials arranged in an ordered fashion for sub-diffraction imaging applications.
Checkout the video:
ua-cam.com/video/QuVBe12Zz-c/v-deo.html
so how long until i can download battery life for my phhone? and how much will the subscription be?
I hope u were in early on the stock. Great video bro
Is this content the same for Metamaterials? Because Metamaterials will be merging with Tourch ticker symbol (TRCH)
I love the video!!! Meta!!!
so they made something like a magnetic transistor? that's amazing!
Butterfly wings also fall into the category of meta materials. Their color is due to the nano structure scale. So in the future we have yet to see the ultimate development of miniature telescopes, as the meta material becomes the function of multiple lenses with nano structure scales, similar to butterfly wings emerging from worms. The butterfly effect across meta space is faster than the speed of light, breaking through many higher meta dimensions and nano structure scale.
I have that target nasa shirt. But I had to buy three because the first was too small, the second time I forgot and bought a small again. The third was the right size.
This is fascinating
When you said "these" in the title I was kinda hoping for examples. Like, "this material has this structure so it looks like this."
I like it. Subscribed.
If the TV show "How I Met Your Mother" was about nanotechnology:
"How I Met-A-Material."
10/10 on that joke
Not your finest joke, Therion.
Im used to more quality master
@@thomaswijgerse723 Yeah, I'm not happy with this one. I like the "metamaterial" pun, but my set up for it was terrible :(
I'll place an order on those spectacles!
do it! do it! the video of invisibility would be awesome sauce!!!!
Kerzegast did a Video on how to build a Dyson sphere/swarm. In reference to the swarm of energy reflecting plates we would need to build the swarm; I wonder how we could apply metamaterials to the construction of such a device 🤔
that channel is my faveratite
i bet you can see the swarm metamatirials would be a yes-go
Meta materials are mesmerizing
Remember the Seiko kinetic watches that came out in the nineties? No? Well, they used the centrifugal forces of your swinging arm to charge the watch. Considering the wearables market has grown now, I'd love to see metamaterials used in our accessories and textiles that take Seiko's concept to the next level, finding a way to use these nanostructures to generate electricity for our high tech lifestyles.
julian is by far my fave, can we see more of him please?
Got a question about the gold example: Does anybody know whether or not this aplies to rose and white gold? Are they maybe naturally happened metamaterials, or do they get their apperent colour a different way?
Rose gold and white gold are alloys not meta materials, rose gold specifically is copper and gold , and white gold is platinum, silver, & gold
Meta materials have more to do with the arrangement of the molecular superstructure than its chemical composition
Now I can make crazy mugs that you can eat out of
"4 years, 3 sets, and one name change ago"
Lmao.
can we get a part 2 on this video?
Can we use this to Interact with gravity fields
Julian Huguet is an awesome person! He is a journalist,gamer and a science person!
You say the process at @3:06 gave off terra Herz radiation but the synchrotron gives off X-rays. The complete opposite side of the electromagnetic spectrum. While it is still cool ( usefully applications in security and such) it will never be replacing a synchrotron.
Hey man have you been working out?
Looks good!
Is there a good book te learn more about how these work?
Unrelated, but the title got Me thinking: If It's found in Reality, it's a part of it's Nature. This is knew (to the video's general fan base's) knowledge of an occurrence in Space-Time that abides by physical laws like Everything else. It's "contemporary" understanding and interpretation of sciences and maths that are apperantly ever-growing (beautifully).
I remember when the other meta video was uploaded. I was amazed then and I’m amazed now
Could you plz give their links..?
Looking at your eyes and how your glasses warped them when you moved your head made my head hurt. It’s an interesting effect. Anyone else notice it?
Invisibility is cool but what about Star Trek holodeck?!
Be via smart contact lenses, then a full body suit with all over pressure pads, to duplicate whatever you're touching via pnumatics?. No idea what I'm talking about. But it kinda sounds right.
be =VR . Oops.
Or what about a Star Trek phasing device? Now that would be really cool.
Yo this stuff is so meta, im designing a rotary stirling engine and this would be perfect for heat transfer using meta materials. Make the perfect engine with this stuff.
1:04 the caption is misquoted. Au(100) is the crystallographic plane itself. Your source has it properly written as "image of surface reconstruction on a clean Gold (Au(100)) surface." Y'all should really just have said gold if you weren't going to use the rest of the words, because this isn't the Au(100) plane in the bulk (hence "surface reconstruction"). I know y'all have a matsci degree over there somewhere.
Okay...
So a tiny "chip" can now do what it used to take a whole building to do?
(Sounds familiar)
Doesn't this tie in with the recently declassified US research document from 2010 on the then "state of the art" in metamaterials?
I mean is it such a huge stretch of the imagination to think Salvatore Pais patents might be close to realisation, if THz frequencies can be produced at this scale then surely they can be utilised in compact and miniature systems... Like the CFR.
Could metamaterials be the key to fusionpower?
so we are basically building stuff on mini mode?
First the computers shrank from the size of building to something you can hold on your hand, and soon your everyday Synchrotron is gonna shrank too damn time flies fast.
1:03 The gold nanoparticle at nanoscale always exhibits red in color due to quantum confinement. Yeah altering the structure could vary the color a little bit from red, but definitely would not be yellowish. Great video tho. Cheers.
That vid was so Meta!!
Is this the same as butterfly wings? It's because the microscopic patter in them were they get there color.
Good video thank you.
Do a follow up video with what Metamaterials MMAT does
Does it has military application? Such as Clocking?
Can they be used for space radiation shielding?!
The title should have been "beyond what's found in nature" as its still a part of nature we humans changed. Unless you are saying its from outside of this universe?
no
Nope. The colours on butterfly wings are also derived from physical nano structures. "beyond what's found in nature" is just clickbait.
Actually that's ironic as butterflies use micro structures to interfere with the incoming light. That's why there so colorful , same for peacocks as well. But no, the physics is the same every were in the universe.
To 'go beyond' is not explicitly synonymous with 'separate from'.
Well you don’t see green gold in nature.
This is Beyond Science
The remark about your coke bottle bottoms made me laugh :D
Sounds like they are becoming more and more relevant in the new meta
can u meta Valarayin steel?
Metamaterials sound like something I would read about in a sci fi novel.
Right, because I'm still so used to wiggling my antenna around on my 1950's TV...
A scanning tunneling microscope can NOT see color at the nanoscale. That image you provided is a arbitrary color scale based on topographic data. That color scale is very common for probe style microscopes such as STM and AFM which I have worked with a lot.
Super thin/lightweight VR headsets with meta-lenses :)
What materials though?? besides gold
I'm glad that guy from the "new guy" is doing UA-cam videos.
Are we getting a video on invisibility then? 🤔♥️
