Can you explain why we are applying those boundary conditions along the y and z axis? And what is the eigenmode analysis whether similar boundary conditions apply there also
Thanks for the video, I implemented with same conditions and I got resonances at 5.5,8.2 and10.5 GHz which is different from the paper. And also please explain how this structure is better than the structure with spits on outer ring but no splits on inner ring. Thanks in advance.
Plz explain the boundary condition you have used ,why you used zmin= Et= 0 and Zmax = open ,plz reply soon.because in your other video you have used conducting wall for simulation .plz explain all these conditions.
how do you know that the reflected wave is polarized in the opposite axis (x-y)? is there any direct correspondance between the plots that CST shows you and the graphs shown in the paper?
Thanks for the video. if have to design a unit meta reflector cell at 2.4GHz how should i approach is there any expression regrading structure dimensions and reflection.
Hi, I am simulating a frequency selective surface and I have used your method for finding the S-parameters but I also want to test it in the Transient solver to study the far-field behaviour around my model by using the same model but with periodic boundaries instead of unit cell boundaries but whenever I test it out the model seems to ignore the S-parameter behaviour that was found in the F-solver. Is there a way to fix this?
Hello sir, ur video it’s very help me. but i wanna ask u, can this tutorial be implemented for an anechoic chamber at s-band frequencies ? i hope u kindly to answer this question i’m very interesting for learning this CST, thank u sir 👏🏻
Hello, Sir First of all, thanks for this wonderful video explanation about how to build FSS on CST. I intend to design a FSS (no idea if I use a single or multilayer FSS) for a ressonant frequency of 60 GHz with 30 GHz of Bandwidth. So, I have a question: how to generate a good quantity of measures for my FSS in way to see the optimun result?
You can select the bigger rectangle and thes select the other one (the one you want to cut it from the other) then press substract (booleen option), it's better.
hi, in ring part, i am unable to cut by applying the settings you mentioned. video stopped at 1045 and at 1046 it was cut..... where as it does not actually. kindly tell me what parameters you changed to apply this cut. regards
there are different technique how to design ebg i.e for single band or multiple ...and add with micro strip antenna ... EBGs are different from Metasurfaces
Hi sir, I appreciate your video, and this is very useful for me, thank you., But I am stuck in a problem. I tried a lot in designing metamaterial antenna, and want to obtain some desired results. But after so many attempts, I am no where. I designed atleast 35 metamaterials antenna, but not able to understand what dimensions I chose, so that required results are obtain. Please help.
@@Mathswithahmad Thank you. I am working on a design for metamaterials with permiability near zero at 13.56 MHz would you happen to have a few tips or designs that could help me ? Thanks in advance.
Sir, can u please provide the paper from which this structure is designed
why i cant cut in 10:46 already use the boolean substract but nothing happen
Great job bro. We really appreciate that.
Could you also show us how to simulate an array of unit cells, say 4x4 unit cell array metasurface?
you add nickel meterial brick for cut.it works.but i think using the shell solid tool and boolean- operations may more reasonable :)

Why we are getting two waves in the in s parameter output and why we are getting 3 resonance frequency in one wave? Please explain the output part sir
please also show how to change incident wave.like x polarized and y polarized
yes please

For high frequency, your fss unit cell dimensions goes to decrease and for the band the structure geometry matter...
what's the value of s??And plz mention all parameters.
read the paper
What’s the value of s?
