Hello Raghwendra,
I already worked with graphene simulation in COMSOL Multiphysics, in my case it was for a 2D photonic crystal waveguide, you can find more information here: Conference Paper Reflectance and transmittance spectra of a photonic crystal ...
But in a nutshell, in your the Electromagnetic Waves, Frequency Domain interface, you can represent graphene using a surface current density condition or a custom material with complex conductivity. I used the Kubo formula to define the conductivity of graphene.
If you have any specific question, please let me know.
Best Regards,
Marcos.
Dear Marcos Moura,
Thank you very much for answering the question. I tried to do the simulation in the RF module, frequency domain. The problem is that the thickness of the single-layer graphene is 0.34 nm, which causes the meshing complication. So, I used the transition boundary condition at the graphene interface as per the recommendation of the COMSOL Multiphysics guidelines, but I was not able to achieve the result. If I use the surface current density, then what will its value be? If I use the custom material, then there will be a meshing problem due to the thickness of the graphene layer.
