Abstract

A recently developed technique for rapid calculation of the Green´s functions in a rectangular cavity combined with a surface integral equation formulation and method of moments (SIE-MoM) is applied for full-wave modeling of arbitrarily oriented conducting objects inside a rectangular enclosure. In a multiply coupled resonator structure, each rectangular cavity with apertures of arbitrary shape and orientation on its walls is modeled by a generalized admittance matrix (GAM) obtained through SIE-MoM. Both combline and dual-mode disk resonators with tuning screw are considered for demonstration of the new approach and a remarkable computational efficiency is observed. A commercial EM simulator is used to verify the numerical results with excellent agreement.
