Abstract
Broadband electromagnetic wave absorbers are of practical importance in many fields. Current absorbers with multilayered configurations at high frequencies suffer from fabrication challenges and design complexity. In this study, we realize a broadband, wide-angle, polarization-independent, perfect infrared absorber with conventional pyramid configuration but only employing one single transparent conductive oxide material without using multilayered design. A transmission line model is introduced to rein the complex frequency responses. Full-wave simulations give consistent results with theoretical predictions. This simplified configuration might relieve the fabrication and design difficulties, exhibiting great potentials in the applications of energy harvesting, IR detection, and imaging systems.
