DESIGN OF TERAHERTZ BIO-ABSORBER USING PLUM FLOWER CURVES
Abstract
A double peaks bio-absorber, which includes two metal layers and one dielectric layer, is proposed. The surface metal layer of the bio-absorber is a square array that consists of a plum shape metal cell that can produce double resonance absorption. By studying the surface current and electric field z-component, the double peak is shown to originate from the two distinct resonance modes of the plum flower curves induced by the incident electromagnetic wave. Due to the symmetrical structure, the proposed bio-absorber is not sensitive to the polarization direction of incident waves and can maintain high absorption rates in a wide, range of angles.
