A Tunable Terahertz Metamaterial Absorber Composed of Hourglass-Shaped Graphene Arrays

A Tunable Terahertz Metamaterial Absorber Composed of Hourglass-Shaped Graphene Arrays

In this paper, we demonstrate a tunable periodic hourglass-shaped graphene arrays absorber in the infrared (IR) and terahertz (THz) frequency bands. The effects of graphene geometric parameters, chemical potentials, periods, and incident angles on the pure absorption characteristics are studied by u...
