Role of Resonance Modes on Terahertz Metamaterials based Thin Film Sensors

Abstract We investigate thin film sensing capabilities of a terahertz (THz) metamaterial, which comprises of an array of single split gap ring resonators (SRRs). The top surface of the proposed metamaterial is covered with a thin layer of analyte in order to examine various sensing parameters. The s...
