Abstract
A new full-wave electromagnetic analysis method
based on the Boundary Integral Resonant Mode Expansion (BI-RME) is presented in this paper. The technique allows the
computation of the broad band circuital response of arbitrarily
shaped cavity filters. The coaxial excitation of this kind of
filters is rigorously modeled by taking into account the high
order modes on the coaxial aperture. A singular decomposition
algebraic procedure has been implemented in order to obtain
the solenoidal and non-solenoidal counterparts contributions of
the electric current density inside the cavity needed by the BI-RME formulation. This method is simple and avoids some issues
associated to star and loop based functions which are typically
used for the same purpose.
