How to simulate the transverse magneto-optical Kerr effect with S4

[samehole]

TMOKE, The form of the dielectric tensor is[ε0 , 0 , -iε1; 0 , ε0 , 0 ; iε1 , 0 , ε0],But the reflectivity I get is the same as the dielectric tensor is [ε0 , 0 , 0; 0 , ε0 , 0 ; 0 , 0 , ε0]. Only when the dielectric tensor is [ε0 , -iε1 , 0; iε1 , ε0 , 0 ; 0 , 0 , ε0],reflectivity will change. Is S4 only able to calculate PMOKE?

https://web.stanford.edu/group/fan/S4/lua_api.html If you look at the AddMaterial documentation here, I believe the off-diagonal elements are ignored and assumed to be zero.

Sorry to bring this up again after 5 years, but I'm experiencing a similar issue with an anisotropic dielectric tensor. If S4 ignores the off-diagonal elements, then
[ε0 , -iε1 , 0;
iε1 , ε0 , 0 ;
0 , 0 , ε0]
shouldn't produce a different result than
[ε0 , 0 , 0;
0 , ε0 , 0 ;
0 , 0 , ε0]
yet according to OP it does. Something fishy is happening with the way the dielectric tensor is treated.
