Numerical Validation of a Multiport Network Model for Reconfigurable Intelligent Surfaces using a Full-Wave PEEC Simulator

The core message of this article is to validate an analytical multiport network model for reconfigurable intelligent surfaces (RISs) using a full-wave numerical simulator based on the Partial Elements Equivalent Circuit (PEEC) method, demonstrating the effectiveness of the analytical model and the appropriateness of the PEEC method for electromagnetic modeling of RIS-assisted wireless links.
