Abstract

The partial-element equivalent-circuit (PEEC) method is generalized to include multilayer dielectric interfaces. The boundary between two different dielectrics is treated as a new region to develop an interface Green´s function. The interface Green´s function is subsequently used to calculate the capacitances and inductances of interface surface cells. The method is first verified, using a microstrip to evaluate the quasi-static capacitance, with the method of Wheeler. It is then extended to the PEEC formulation and applied to coupled microstrip-line filter with multilayered dielectrics. The results are compared with that of the method of moments. Agreement is found in the prediction of resonant frequencies and S-parameters.
