Abstract

In this paper, we experimentally analyze the absorption of two metamaterial perfect absorbers made of different materials: gold (Au) and tungsten boride (WB, a refractory ceramic). We show that WB has wider absorption bandwidth than that of the gold counterpart. Moreover, WB reveals better performance with absorption more than 90% over the spectral range from 950 to 1400 nm.
