Dear All
COMSOL follows exp(-iwt) modeling in the and hence the absorption of the material is given by imag(permittivity) >0.
If I want to simulate a gain medium, is it trivial to replace the imag(permittivity) < 0 ? or am I missing something.
The other question is regarding : how to set the circularly polarized light
Assume wave propagates in +x direction
E =(0 0 1) implies linear polarization
if I set E = ( 0 i 1) does this mean its a circularly polarized light since there is phase difference between Ex and Ey?
Any help will be appreciated.
Thank you.
