Abstract :
We present and discuss infrared magnetoplasma reflectivity and surface polariton modes in Ga/sub 1-x/N/sub x/As. It assumed that the sample is characterized by a magnetoplasma dielectric tensor. Surface polariton dispersion for two component magnetoplasma was calculated from reflectivity spectra data. An interesting feature of surface modes in Voigt geometry is nonreciprocalicity, which means that the frequency changes when the direction of propagation is reversed.
