I have watched all your videos..Thanks a lot.Simple and clear explanation..👌
Your positive comments motivates me.
Teachers like me just wants positive comment from student.
Love from you guys means a lot to me.
My goal is to create largest community of engineers in entire globe. Please help me by sharing this playlist with your friends.
Sir your teaching is awesome. Your lectures helped a lot of students
Ghanta. Do u think this a proper way of teaching these fundamentals!? 🙄
i was never clear with microwave electronics basics...now because of u i can even crack competitive questions..
i dnt know who the hell can dislike ur vedios...
gr8 work sir...hats off
Kirti Kansal video*
day aftr tomorrow is my exam... im totally dependent on u. i havent even bought the text book.
+sumit roy : which examination. Microwave?
+sumit roy : see the course content as per examination. I am sure you will get 90% of your course from here in my playlist
yup.
well i have sorted some videos from ur playlist according to my syllabus . i think , i ll get through the exam. microwave engg playlist is very helpful .thanks a lot sir. keep up the good work.
p.s- i ll tell u, if i pass.
+sumit roy : you will for sure. And your welcome.
Thank you so much!! very nice explanation.

Superb sir
Thanks for such a nice video
Ur way of explaining vry gud
I m watching ur all video n I totally clear my all concept..
Thanks alot
+Sonal Khandelwal : your welcome
In scattering matrix videos of e,h,magic you have written "input at port 1 and output at port 2" as S21 and in this video you have written input port first that is S12 , which one is correct ?
Input at Port a output at Port b is Sba
Very clear explanation thabks a lot . It really helped me alot !! I would like to ask you to Speed up the video that's it ...
I will take care of your suggestions.
Even you can see videos at 2x or 1.5x speed.
Yes, i did that thing... I've watched some of your videos and you asked us to give suggestion if any ... I suggested that's it😇 anyway thanks for the reply
Your welcome dear 🙏
tank u so much sir bht acha smj aya.......thankxxxxx.....
Awesome explanation
sayantan mondal thanks
best explanation so far on youtube!!!
Awesome lecturer sir

thank you sooo much sir
maza aagya
Your welcome
pls remove so many ads, the content of video as in the information and all is very well explained , thanks for that.
Sir please put bethe or single hole directional coupler
Suppose we have two 2 x 2 waveguide couplers (couplers A and B) that have identical channel geometries and spacings, and are formed on the same substrate material. If the index of refraction of coupler A is larger than that of coupler B, which device has a larger coupling coefficient K? What does this imply about the device lengths needed in each case to form a 3-dB coupler?
what are you saying @19.07 time, S12 as input at 1 and output at 2 but earlier you told opposite of that in scattering parameter video
i agree with you
Sir everything is good but will you increase your voice for better understanding thank you 😊
sir plz explain Rotating coupler
Tomorrow I have my exam and I am totally dependent on u..please help.
Best wishes for exams
Helpful
Thanks from me
Sir pls tell me which reference book shud i follow
excellent lecture , One suggestion bro, most of the related topic are used reverse notation for port 3&4. So sometimes it make confusion.
Thanks and God bless you
Happy Diwali Brother,< Nice job >
Sir, in the next vdo u have shown that C = - 10 log(pi/pf). Then which formulae we should use?
sir how to calculate power at isolated port when power at all the other ports are calculated?
I have explained few examples even, I think it may help you for that , just go through my microwave playlist
Hi sir ... excuse me I have a question.... we take this subject at college but about the matrix that we get at the last of the video in my college lecture the Q that was in the matrix was with j ... I mean jQ .. just I wondered why did we get that j and how ?? Please please answer 🙏🏻
Totally understandable👏🏻👏🏻
Maintain same level of explanation in upcoming videos😊
Thank you very much
Your positive comments motivates me, my goal is to create largest community of engineers in entire globe, so please help me for that by sharing this lecture series(playlist) with your friends in social media (watsapp, telegram etc). Thanks and welcome 🙏
output phle aege na input k..last m
Sir S12 means 2 input and 1 is output but u are telling in different manner
sir can you explain me why 10db and why 3db...i mean what is the use of these values and why we are calling them as 10db and 3db couplers
In 3dB coupler, we couple half power ideally in coupling port.
In 10dB coupler, we couple 10% power ideally in coupling port.
@@EngineeringFunda sir i know the function but didn't understand those values.example: why 5db coupler is not termed as equal splitter
See the calculation of dB.
And do calculate some basic examples like.
3dB = 10 log p
So here p will 1/2.
10dB = 10 log p
So here p will 1/10.
Magic tee as 3 dB coupler.. Please solve
Can you explain about 3 port directional coupler using s parameters
Here back port is terminated with perfectly match load, you can say it is three port directional coupler
@@EngineeringFunda thankyou
19:13 forward power S21=S34=p
lly Coupled power S41=S32=q know na sir ?
Yes but then they are symmetric.
Therefore it doesn't matter.
thank u sir
+siddhu janai : your welcome
Tq ...so much sir

Your welcome
How 3 db is divinding half and 10db in 90-10
3 = 10 log k
Where you will get k = 0.5
10 = 10 log k
Where you will get k = 0.1
S23 means, input at port 2 and output at port 3 or input ar port 3 and output at port 2???
+Thilina Tharanga : S23 meaning power transferred from port 3 to port 2. Means input at port 3 and output at port 2
Lucid Explanation
+raman kavuru : thanks & your welcome
naice
14:43 jai hind dosto, big boss se call chala aya😂😂
What is the need of identity property here
Single hole directional coupler is same as bethe hole
bethe hole directional coupler please
What is S* matrix
It's there in the video
Tesla called at 14:44
are bhai bhai bhaii🤣🤣🤣
dude so many ads in your video. half of the time i got irritated by that... knowledge part is good but ads suck... 2-3 are fine but 6-7? makes no sense at all.
Two hole direction coupler?????
+parasa praveena : two waveguides are connected with holes. One is for coupling and other is for back in reverse direction signal
Engineering Funda Bethe hole means????
+parasa praveena : don't know what is Bethe hole? Do you?
It is also type of direction coupler but don't know what is it. Try to make vedio on it
Didn't Notice it was 21m long
Isn't the coupling factor formula mentioned @7.15 wrong?
It is correct
there is a minus sir. ratio is output to input you've mentioned input to output
Learn something abt how to use terminology
3db is not hlaf power please pay attention to this
please remove the advertisements from the video ....we cannot concentrate ....it is really very very annoying
too many ads
sir please dont use sketch pens use normal pens to explain
Ok
irritating adds
first switch off your mobile.........................
Hello Is ithere somewhere a drawing "how to build a 3db divider in a waveguide" practical example !
thanks
please remove these fucking ads in between,it hampers the total concentration
Wonderful explanation
