Spatiotemporal varying relative permittivity based non-reciprocal transmission

Please login with a confirmed email address before reporting spam

I am trying to reproduce the paper: Complete optical isolation through indirect interband photonic transitions

The non-reciprocal transmission they have demonstrated in fdtd by their in house simulation code. I want to reproduce the same results by spatiotemporal varying the relative permittivity in comsol multiphysics. I am not getting how to do/implement it. Any helpful constructive suggestion is highly appreciated.
