A Band Enhanced Plasma Metamaterial Absorber Based on Triangular Ring-Shaped Resonators

In this paper, a novel way is proposed to realize a broadband absorber, which is based on the plasma metamaterial with the triangular ring-shaped resonators. Each unit cell of the proposed absorber includes three layers, which are metal layer, dielectric layer, and solid-state plasma (SSP) layer, respectively. The top layer is composed of the truncated SSP triangular ring-shaped resonators and the...
