Theory of a Solid State Plasma Waveguide in a Transverse Magnetic Field

Abstract

Electromagnetic wave propagation through a surface plated n(or p)-type semiconductor in a transverse magnetic field is investigated theoretically. Two types of waves exist. One is a TE-wave which has a strong spatial asymmetry dependent on both the magnitude and the direction of the magnetic field. The other wave has a longitudinal component of the electric field and reduces, in the low frequency limit, to a helicon wave standing in the direction of the magnetic field and traveling in the direction perpendicular to the magnetic field. The theory is in good agreement with the experimental results of Toda.
