Rectangular waveguide with magneto-dielectric rectangular-shaped rods

An algorithm for computing the propagation constant, field structure, and limiting power in rectangular waveguide loaded with inhomogeneities is constructed by the method of partial regions and materialized in FORTRAN language for the Minsk-32 computer. Convergence of the solution to an exact solution is tested by a numerical experiment. The peak electric field strength in the guide is assumed localized and permissible transferred power in the traveling wave mode is calculated for a lossless waveguide load and ideally conducting metallic guide walls. Field distributions and power flux densities are obtained. Appreciable discrepancies between experimental and predicted values are ascribed to the disparity between the mathematical model and a real system (discreteness of guide inserts; mismatching; defects in bonded joints between ceramic inserts and waveguide walls) inevitable at the present state of the art.
