Enhanced PEEC modeling for embedded RF passives of irregular shapes

This paper presents an enhanced partial element equivalent circuit (PEEC) for modeling embedded multi-layered passives of irregular shapes to meet with the increase of complexity of the electrical system. The proposed PEEC model consists of the improvement of the meshing scheme to model irregular geometries instinctively and also the derivation of a new set of numerical formulations to get the partial inductance and capacitance. Two examples, including a circular spiral inductor and a high-pass filter, have been simulated by this method and the commercial software, high frequency structure simulator (HFSS). The agreement between these two simulation results proves the validity and accuracy of this generalized PEEC model.
