Generalized admittance matrix of arbitrary E-plane waveguide junctions by the BI-RME method

This paper describes an efficient boundary integral technique for the determination of the quasi-static generalized Y-matrix of building blocks of E-plane waveguide components. This matrix is a part of the pole expansion of the Y-matrix in the frequency domain. Calculating the remaining part by the BI-RME method, and using the technique described in this paper, we obtain a very efficient algorithm for the wideband modeling of E-plane building blocks. Some examples demonstrate the efficiency of the algorithm.
