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...
This paper describes the modeling of the different types of losses in substrate integrated waveguide (SIW). In particular, radiation leakage, conductor losses, and dielectric losses are considered. The modeling is based on the Boundary Integral-Resonant Mode Expansion (BI-RME) method. This method permits a fast and accurate determination of the wideband frequency response of SIW interconnects and...
