Multiplexing Integration Meta-Absorber in an Ultrathin Planar Board

Abstract

Meta-Absorbers

In article number 2401738, Tong Cai, Chunsheng Guan, Wenye Ji, and co-workers propose a multiplexing integration meta-absorber in a one-layer planar board by harnessing the coupling of four resonant modes, achieving an ultra-thin thickness and an ultrawide absorption band. Our work presents a feasible absorption strategy that is closer to practical applications and may pave a way for the development of ultra-thin meta-devices.
