Characteristic Modes of Frequency-Selective Surfaces and Metasurfaces from S-Parameter Data

Schab, Kurt LU ; Chen, Frederick W. ; Jelinek, Lukas ; Capek, Miloslav LU ; Lundgren, Johan LU and Gustafsson, Mats LU orcid (2023) In IEEE Transactions on Antennas and Propagation 71(12). p.9696-9706
Abstract

Characteristic modes of arbitrary 2-D periodic systems are analyzed using scattering parameter data. This approach bypasses the need for periodic integral equations and allows for characteristic modes to be computed from generic simulation or measurement data. Example calculations demonstrate the efficacy of the method through comparison against a periodic method of moments (MoM) formulation for a simple, single-layer conducting unit cell. The effect of vertical structure and electrical size on the number of modes is studied, and its discrete nature is verified with example calculations. A multiband polarization-selective surface and a beamsteering metasurface are presented as additional examples.
