%X This paper presents a simple and alternative approach
for the analysis of inductive waveguide microwave components. The
technique uses a surface integral equation formulation, in which the
contours of the waveguide walls and of the inner obstacles are all
discretized using triangular basis functions. In order to avoid the
relative convergence problem of other techniques based on mode
matching, an alternative port treatment is used. The technique is
based on the application of the extinction theorem using the spatial
representation of the Green's functions in the terminal waveguides. In
addition, the Fast Multipole Method is proposed in order to reduce the
computational cost for large problems. Different complex structures
are analyzed, including microwave bandpass filters with elliptic transfer
functions, waveguide bends and T-junctions. Results show the high
accuracy and versatility of the technique derived.
