Volume and surface magnetoplasma polaritons in semiconductor layer

New features in propagation of plasma polaritons in a plane layer of magnetoactive semiconductor plasma with symmetric and non-symmetric dielectric environment have been studied. Dispersion and polarization characteristics of magnetoplasma oscillations at different values of boundary medium parameters have been found. Qualitaive criteria of resonance interaction of surface magnetoplasma polaritons have been determined propagating on the opposite boundaries of a semiconductor sample. Plasma waves in the semicnductor magnetoactive layer boundaring with a dielectric of finite thickness have been investigated
