AbstractIn this article, a passive full-wave partial element equivalent circuit (PEEC) model is formulated for modeling electromagnetic (EM) problems with finite dielectrics. The proposed PEEC model is a substantial extension of the generalized PEEC model for problems of multiple conductors in free space. The proposed generalized PEEC model reflects the physical radiation mechanism of an EM problem with finite dielectrics. The radiation effects, both from conductors and dielectrics, are incorporated in real-valued frequency-dependent inductances and resistances, while capacitances remain to be frequency invariant. Consequently, the resultant circuit model of the proposed PEEC model is numerically verified to be more passive than the existing PEEC models. The minor passivity violation can be amended without altering the circuit configuration. To model a dielectric with the irregular-shaped surface, a triangular meshing scheme with Rao-Wilton-Glisson (RWG) basis is used. The generalized PEEC model provides a passive circuit model for both the frequency- and time-domain modeling of an EM problem with finite dielectrics. The passivity and accuracy of the generalized PEEC model are validated by an low temperature co-fired ceramic (LTCC) multilayer filter module, two dielectric resonator antennas, and a patch antenna.
