Plasma-Filled Waveguide with Axial Magnetization. II. Scattering by a Section of Finite Length

The problem of mode conversion and scattering by a finite-length section of magnetoplasma-filled waveguide is formulated in matrix notation. This formulation becomes increasingly exact as the dimensions of the matrices (i.e., the number of modes considered) increases. The desired reflection- and transmission-coefficient matrices are readily evaluated with a digital computer. Computations of TE010-mode reflection coefficients indicate that good accuracy can be obtained with a fairly small (∼10) number of modes. Large errors result from considering only the incident (TE010) mode, however.
