Field Distribution in a Magnetoplasma-Loaded Waveguide at Room Temperature

The boundary value problem of a rectangular waveguide loaded with a thin slab of transversely magnetized semiconductor is solved with the help of a variational method. An electric field distribution showing strong nonreciprocal characteristics is obtained theoreticrdly, and is in good agreement with the experimental results performed with very thin slabs of n-InSb at room temperature.
