Faced with the challenges of increasing operational frequencies and switching rates of modern electronics devices used in electrical systems, there is an extensive need for high frequency models (up to a few gigahertz) for electrical components like bandpass filters, couplers and power distributors. This paper presents the application of partial element equivalent circuit (PEEC) theory for the creation of electromagnetic models for bandpass filter. A technique to obtain S-parameters using the PEEC models for a bandpass filter structure is presented. The electromagnetic field couplings are separated in mutual partial inductances and mutual coefficients of potential giving a correct solution from DC to a maximum frequency determined by the meshing. The PEEC models are validated by comparing simulation results against other established modeling method, method of moments (MoM), and show good agreement. The model created by PEEC theory, could be helpful in the designs and diagnostics of bandpass filters and other electrical system components.
