An original generalized-admittance-matrix (GAM) approach for the analysis o
f multiport junctions in rectangular waveguide having an arbitrary circular
-rod inset is presented in this paper. The method is based on an efficient
computation of the GAM for the blocks that compose the structure. The effic
iency is due to the fact that, for each block, the full three-dimensional G
AM is obtained by solving a set of uncoupled two-dimensional problems. The
accuracy and efficiency of the method developed have been assessed by compa
ring the results obtained with some measured data and with data obtained by
the finite-element method.
