Analysis of Multitone, Multiconductor, Spatially Discrete Traveling-Wave-Modulated Loop Networks

Abstract

This work presents a spatially discrete traveling-wave modulated (SDTWM) loop networks, which exhibit cavity-like behavior and support discrete spatiotemporal modes. We introduce a computationally efficient method, based on the Interpath Relation, to analyze periodic networks using a single unit cell. This allows characterization of driven systems with single-tone, multitone, and multiconductor loop configurations. The framework captures both multimodal and multifrequency harmonic interactions and is extended to compute the spatial Green’s functions of such loop networks using analytic array scanning (AAS). The analysis of example designs, such as an electrically small antenna and a nonmagnetic circulator, is presented. These examples confirm that the proposed approach is computationally efficient and offers physical insights, making it well-suited for the optimization of multifunctional and nonreciprocal SDTWM electromagnetic systems.
