How to define an anisotropic material such as phosphorene in COMSOL Multiphysics?

17 February 2025 0 6K Report

Hi, dear researchers,

I want to design an optical fibre sensor using phosphorene. As you probably know, it is an anisotropic 2-D material and needs to define its matrix in COMSOL, but I have no information about it.

How can I define it?

(Based on the Eq. 3 in the attached file)
