Applications of the partial element equivalent circuit method in computational electromagnetics simulation: An overview

Abstract

Computational electromagnetics (CEM) simulation is employed in diverse applications to analyze electromagnetic (EM) fields and waves, providing critical insights essential for design and optimization. Among the various available CEM techniques, such as the finite element method (FEM) and the finite-difference time-domain (FDTD) method, the partial element equivalent circuit (PEEC) method is an upcoming and preferred technique in certain applications due to its capability to integrate EM and circuit simulations, as well as its reduced computational cost. Consequently, publications based on the PEEC method have exhibited an increasing trend in the recent years. This study provides a comprehensive overview of PEEC-based applications across various fields to address prevailing problems in these applications. The survey categorizes the publications based on the type of application and provides detailed information on the techniques used and the results obtained. This work also briefly highlights the growing trend of adopting model order reduction (MOR) techniques, emphasizing their compatibility with the partial element equivalent circuit (PEEC) method to achieve more efficient and effective solutions. This review paper is valuable for researchers and engineers in related fields, aiding them in pinpointing future research opportunities and effectively employing the PEEC technique.
