Straight wedge absorber geometry optimization for normal and oblique incidence
Straight wedge absorber geometry optimization for normal and oblique incidence
—This paper presents a topology for improving the performance of straight wedge absorbing materials at oblique angles of incidence. The optimization process is based on a genetic algorithm and allows one to obtain a low reflection coefficient within a wide band of frequencies. We investigate the performance by comparison between the straight wedge absorber and the optimized wedge absorber. These wedge absorbers were simulated in the CST Microwaves Studio software, using a polymer foam material.
