Perturbation Analysis of Rectangular Waveguide Containing Transversely Magnetized Semiconductor

The boundary value problem of rectangular waveguide, filled with transversely magnetized semiconductor or plasma, is solved by a perturbation method reported earlier. The solution by first-order theory is compared to the results of an experiment in which surface currents in the guide wall due to perturbed and unperturbed TE_1,0 wave in N-type Silicon are sampled and segregated. Theoretical and experimental results are in excellent agreement.
