Abstract :
A fast converging and stable moment method solution for the current distribution on arbitrary size rectangular obstacles mounted transversely inside the rectangular waveguide has been developed. A special arrangement of piecewise sinusoidal and pulse basis functions has been utilized to determine the transverse current distributions on the obstacles and their scatterings in the waveguide. The method has been compared well with the Marcuvitz´s results for the inductive and capacitive posts and the experimental data of an arbitrary size rectangular obstacle
