Article Synopsis
- The paper introduces a new theoretical design for a terahertz metamaterial absorber based on surface plasmon resonance, featuring five distinct absorption peaks.
- This structure consists of a gold bottom layer, a silica medium, and a graphene array, with absorption rates reaching up to 99.87% at specific frequencies.
- The design allows for dynamic tuning of absorption characteristics via graphene's Fermi level, offering high sensitivity and wide-angle performance, making it suitable for applications in sensors and optoelectronic devices.
This paper introduces a novel metamaterial absorber based on surface plasmon resonance (SPR). The absorber is capable of triple-mode perfect absorption, polarization independence, incident angle insensitivity, tunability, high sensitivity, and a high figure of merit (FOM). The structure of the absorber consists of a sandwiched stack: a top layer of single-layer graphene array with an open-ended prohibited sign type (OPST) pattern, a middle layer of thicker SiO, and a bottom layer of the gold metal mirror (Au).
