Generating method and generating system of wideband reconfigurable intelligent surface

Abstract

A generating method and a generating system of a wideband reconfigurable intelligent surface are proposed. The generating method includes executing an electromagnetic simulation software to generate a plurality of reconfigurable reflective units, and simulating the reconfigurable reflective units to obtain a plurality of reflection characteristic simulation values corresponding to a plurality of metal patterns; calculating the reflection characteristic simulation values according to an adaptability function to obtain a plurality of adaptability values corresponding to the metal patterns; calculating the adaptability values according to an optimization algorithm to obtain an optimized adaptability value, wherein the optimal adaptability value corresponds to an optimized metal pattern data; and importing the optimized metal pattern data into the electromagnetic simulation software to generate a plurality of optimized reconfigurable reflective units and forming the wideband reconfigurable intelligent surface based on the optimized reconfigurable reflective units.
