I am trying to define a chiral material with the following constitutive relations: D =ϵE +iξB ,H =μ^(−1)B+iξE to generate OAM, However, I don't know how this material can be defined in COMSOL. While COMSOL allows the definition of a an anistropic material, I don't know how I can define bianisotropic materials. similary how can i simulate OAM beams using COMSOL, please help me. Thank you

Hi, Dear Sir/ madam I am trying to simulate Orbital angular momentum beams of photon for optical communication by using chiral media but i didn't get explained in the model builder. I am also tried to modify the Gaussian equation in RF module but i couldn't find the way to modify it. also i tried to use form FDTD but i haven't succeeded yet, please help me. thank you
