This paper presents the application of the Boundary Integral-Resonant Mode Expansion (BI-RME) method to the modeling of waveguide components comprising lossy dielectric materials. The proposed technique is based on the combination of the BI-RME method and of a perturbation approach. The BI-RME method yields the frequency response in terms of the generalized admittance matrix, expressed as a pole expansion in the frequency domain. The inclusion of dielectric losses by the perturbation approach is mainly performed by considering the quality factor of the modes of the cavity obtained by short-circuiting the ports of the circuit. The BI-RME method can be applied to waveguide components filled with a piece-wise homogeneous dielectric medium, by adopting the segmentation technique. Two examples are presented to validate the accuracy and robustness of the proposed method.

“…Thus, the vanishing of surface integrals in (9) gives k n a n = −jωµ 0 b n and that in (10) gives g λ = 0, similar to the corresponding results for closed cavity case. Using these results, the remaining port integrals are those containing the magnetic field H in (11) and (12) become, k 2 n a n − jk 0 η 0…”

An eigenmode projection technique (EPT) is developed and employed to solve problems of electromagnetic resonance in closed cavities and scattering from discontinuities in guided-wave structures. The EPT invokes the eigenmodes of a canonical predefined cavity in the solution procedure and uses the expansion of these eigenmodes to solve Maxwell's equations, in conjunction with a convenient choice of port boundary conditions. For closed cavities, resonance frequencies of arbitrary-shaped cavities are accurately determined with a robust and efficient separation method of spurious modes. For waveguide scattering problems, the EPT is combined with the generalized scattering matrix approach to solve problems involving waveguide discontinuities with arbitrary dielectric profiles. Convergence studies show stable solutions for a relatively small number of expansion modes, and the proposed method shows great robustness over conventional solvers in analyzing electromagnetic problems with inhomogeneous materials.

In this paper the extension of the Boundary Integral-Resonant Mode Expansion (BI-RME) method to the modeling of lossy waveguide components is discussed. The proposed technique is based on the combination of the BI-RME method and of a perturbation approach. The generalized admittance matrix of the circuit, which is provided by the BI-RME method as a pole-expansion in the frequency domain, is perturbed to account for both metallic and dielectric losses. Since the BI-RME method applies to homogeneously filled waveguide components, a segmentation technique is adopted in case of a piece-wise homogeneous dielectric medium. The effectiveness of the proposed technique is demonstrated through examples.
