Detailed Description

Fix class for the linear combination of dispersive media emMedium described by Drude and Lorentz terms.

Dielectric function is assumed to be linear combination of dielectric functions of specified media. This class works in the same way as emDispersionSolver. The only differences are:

• in initialization one needs to a pass list of media emMedium and fill factors
• while recording points one need to pass fill factors for the participating media
