# How to create a 2D h-BN material in FDTD?

#1

Hi,

I am currently work with 2D h-BN simulation in FDTD. I do not how to set up this material in FDTD. Could you give me some suggestions?

Thank you!

Regards,

Hi Eric,

When you simulate 2 dimensional material, such as graphene, you might either assume a certain volume for the 2D material and set the permittivity of the material, or use surface conductivity property, which I find little bit advanced. In either case you might have to find proper formulas that describe your material.

I think the following page would be helpful.
