Simulation of Metasurface Unit-cell | COMSOL Multiphysics

In this video, we will learn how to simulate the unit cell of the metasurface.
The metasurface is the two-dimensional analogue of the metamaterial. It is a spatially heterogeneous array of nanoscale resonant elements (called meta-atoms) that can, in general, alter the amplitude, phase, spectrum and polarization values of an incident wave-front in a very short propagation distance and with subwavelength resolution in the transverse plane.

Very descriptive! Thanks.

[@hmdbaloch]

Please keep uploading tutorials regarding metasurfaces.
Thanks

[@humansineducation4511]

Thank you. Stay tuned for more videos!

[@master7phy]

Very very goooood

[@humansineducation4511]

Thank you for the appreciation.

[@yourchoicerp6650]

Please upload more tutorials.
This is very useful to us

[@humansineducation4511]

Thank you for the appreciation. Stay tunned for more videos.

[@tilkesh]

Thank you

[@sushmajoshi6954]

Very nice

[@krushnaparekh759]

very useful

[@raghunadhasastryrentachint8753]

Krupali, please make a video on designing a 3D parallel transmission line

[@humansineducation4511]

Sure I will make it in future. For while, I found a video that might be useful to you. The link is, th-cam.com/video/olpn0-Uldxc/w-d-xo.html

[@raghunadhasastryrentachint8753]

@@humansineducation4511 yes I have seen this previously, but I got stuck with designing of 3d transmission towers

[@davidagabiti9869]

Nice video, it was really interesting!
i wanted to ask you a doubt, if i want to simulate the unit cell of the metasurface for the vibration and acoustic field could you advise me on which steps should i change from the ones in the video?
I'm doing my master degree thesis on this topic and it would be really helpful

[@humansineducation4511]

Hello David, thank you so much for watching and appreciating. If you want to design the acoustic metasurface, you have to use different boundaries and considers the thermoviscous effects. For such design, please watch below video of Helmholtz kind of metasurface,

[@SAADANWAR-v8n]

Kindly share the video related to effective parameters (mu and epsilon) calculation.

[@tilkesh]

How to arrange the meta atoms to make a metasuface. Do you have any mph file or tutorials?

[@MechaNik_IIT]

Helpful plz make more videos

[@没有巅峰人生永远是上]

thanks very much for the video. 1. Could I ask how to ge the phase in the far field? 2. Do you know how to use far field domain? 3. What is the difference between the selection of full field and scattering field? thanks a lot!

[@sumanjusMontes]

Thank you very much, how could we use this absorption in a layer of a solar cell? please help

[@Rajkumar-wr5cm]

I want to simulating M-I-M structure which is one unit cell of metamaterial . please upload this type video,
thanks for it

[@sumanjusMontes]

How could I do to improve the absorption of this metamaterial? and how could you improve your permittivity?

[@chetanv8345]

Sir Iam working on photonic crystal dielectric structures, Im not able to get the absorption reflection and transmission graphs
Instead there is a arc length vs electric field graph, Iam stuck here. Could you please guide me where is the option to obtain those graphs as Iam new to comsol, Thank You

[@roshankumarsingh7608]

How you can find phase at output?

[@visheshmodi346]

In any metasurface design, phase is also important as the transmission. How can I calculate in COMSOL Multiphysics v5.3?

[@humansineducation4511]

Hello Vishesh! You can calculate the phase by the function called arg(S21)

[@roshankumarsingh7608]

arg(ewfd. S21)?

[@fotoniksuperduper9435]

why you are not using floquet periodicity?

[@MechaNik_IIT]

If you have waves at normal incidence, just use periodic boundary condition. If your incident wave have propagation angle, you must use Floquet boundary conditions to include in-plane components of wave vector.

anyone here who's working on metasurfaces for RCS reduction, please reply back, thanks
