Evolution of Polarization in an Anisotropic Nanocomposite with Resonance Dispersion

The dynamics of polarization in an anisotropic nanocomposite with effective permittivity satisfying the Maxwell-Garnett model has been investigated. It has been established that for circular polarization, depending on the frequency, there exist three bands in each of which the evolution of polarization has a different character. With the help of the Poincar, sphere, states have been identified through which the polarization passes as light propagates in the composite. A small change in the filling factor of the nanocomposite leads to a substantial change in the phase change and the polarization of the wave. The curve of the phase change upon exit from the medium as a function of the wavelength of the incident light has a resonance character.
