Abstract :
A three-dimensional discontinuity problem of a pair of metallic posts with a finite diameter in the TE/sub 11/-mode circular waveguide is solved by the method of moments. Unlike the widely used multifilament representation which leads to a slowly converging series, a multistrip representation is introduced for the post current modeling. Numerical results are compared with experimental data, including those given by the other authors.<>
