Bi-anisotropic medium

Hello,

I am using COMSOL 4.3a and its RF module to simulate electromagnetic structures. I would like to know if it is possible (and if yes, how) to implement fully bi-anisotropic medium ? So far, I was only able to define anisotropic relative permittivity and permeability but I didn't find anything related to the chiral parameters.

Can anyone help ?

Thank you.
