Abstract

Abstract

This paper conducts an equivalence study on honeycomb structures with dispersion characteristics and anisotropy based on an improved S-parameter inversion method. Using three-dimensional electromagnetic simulation software CST and a free-space measurement system, the modeling, simulation, and practical testing of the honeycomb structure and its equivalent flat plate were successfully accomplished. By varying the incident angle of the plane wave, the scattering parameters of the honeycomb model were obtained under both normal and oblique incidence conditions. Through an inversion procedure, the equivalent electromagnetic parameters corresponding to each incident condition were sequentially derived and subsequently applied to the equivalent homogeneous flat plate, thereby achieving the equivalency treatment of the honeycomb structure. The accuracy and feasibility of this method are verified by comparing the simulation and measurement results of scattering parameters before and after the equivalence of the honeycomb structure.
