Dielectric multilayer cavity coupled metamaterial

Abstract

Dielectric multilayer stack metasurface is coupled with a gold mirror forming a hybrid metamaterial that targeting at multiband absorption. The resonant mechanisms responsible for each absorption band are explained in this study. Furthermore, a potential fabrication process has been proposed and demonstrated. This absorber exhibits flexibility in design and feasibility in fabrication, which makes it an excellent candidate for various applications, particularly in the field of sensing.
