Surface Conductivity example

[mahar]

Hello,

I would like to ask if there is a simple example on how to specify surface conductivity in the C++ interface.

If you have an example geometry in mind, particularly one for which known results exist, I will get it working in SCUFF-EM and create an example in the online documentation.

Thank you for the response!
A simple geometry is a simple slab of thickness, say, 20 microns with a 2D material on top. So probably I need two interfaces and define surface conductivity for one of them, correct?

In the following file I have some data for the surface conductivity of graphene (real and imaginary part) in [1/Ohm] for 1-10THz for E_F = 0.1eV and tau = 0.1ps.
http://www.mavidis.xyz/_files/graphene_01eV_T300_tau_01ps.txt (columns: frequency [THz], real(sigma), imag(sigma))

I have calculated the transmission and reflection for a slab of 20 microns thickness, eps = 2.9 and normal incidence using transfer matrix:
http://www.mavidis.xyz/_files/graphene_T_R_slab20um_eps2_9_Ef01eV.dat (columns: frequency [THz], T, R)

I know that one way to do that is to consider the 2D material as a very thin slab but it would be much more useful for me to define it via surface conductivity.

Thanks for doing the work of providing this example calculation. This is something I've been meaning to get around to for a long time, and it's something that other people have asked for, so I am now officially working on it starting today. Unfortunately, I am extremely slow and pedantic, so it's hard to say exactly when it will be ready to go, but I will keep you posted.

Thank you!

I'm also interested in this feature.
