Abstract

This paper presents a simulation-based study of multilayered absorbers. Such absorber structures can be designed to exhibit broadband absorption performance of 52% fractional bandwidth. We discuss the TE, TM incidence angle dependency characteristics of a doubly periodic arrangement of the square, conical and hexagonal truncated stacked lamination prism arrays. Then further geometry modification is made to achieve a dual-band operation with a low profile. The simulation results show that the frequency ratio can be tuned by controlling the metallic via location. The resultant dual-band design has stable absorption performance at different incident angles.
