“…It is also worth observing that the proposed PEEC formulation, which is based on charge and current basis functions, has been found to be more robust towards the so-called low-frequency breakdown, as confirmed in [31] and [32], resulting to be a full spectrum methodology. More refined modeling approaches of time-dependent zero-thickness partial inductances and coefficients of potentials are presented in [33], [34], and [35]; nevertheless, they are not considered in this work, and their application to our problem is left for future investigations.…”

Reconfigurable intelligent surfaces (RISs) are planar, almost 2-D, structures that can intelligently manipulate electromagnetic waves by low-cost near passive reflecting elements. RISs are considered a potential enabling technology for the sixthgeneration (6G) wireless communication systems due to their capability to tune wireless signals, thus smartly controlling propagation environments. This work has a twofold objective: firstly, we present a systematic methodology for characterizing RISs in the time domain, which rigorously includes propagation delays and mutual coupling among RIS elements; secondly, we analyze the RISs through a convolution-based solver that is enriched by a specialized convolution scheme that enables the analysis of systems with complex linear, nonlinear as well terminations. The proposed approach is validated by extensive numerical evaluations against well-established methods based on both frequency-and time-domain analyses, with a varying number of RIS elements, interdistance, and frequency of operation. Index Terms-Partial elements equivalent circuit method, reconfigurable intelligent surfaces (RISs), time-domain (TD) analysis.

“…where δ(t) denotes the delta Dirac function. More recently, rigorous TD expressions for partial inductances and coefficients of potentials have been proposed in [101], [102], and [103] assuming rectangular Manhattan shapes. An effective way to recover TD partial inductances for nonorthogonal shapes of the volumes is to use the modified numerical inversion of the Laplace transform [104] that uses the Cauchy's theorem.…”

This year marks about half a century since the birth of the technique known as the partial element equivalent circuit modeling approach. This method was initially conceived to model the behavior of interconnect-type problems for computer-integrated circuits. An important industrial requirement was the computation of general inductances in integrated circuits and packages. Since then, the advances in methods and applications made it suitable for modeling a large class of electromagnetic problems, especially in the electromagnetic compatibility (EMC)/signal and power integrity (SI/PI) areas. The purpose of this article is to present an overview of all aspects of the method, from its beginning to the present day, with special attention to the developments that have made it suitable for EMC/SI/PI problems.
