Dual-band graphene-assisted metamaterial absorber with machine learning integration for high-sensitivity THz biosensing

Abstract In this work, a compact dual-band terahertz (THz) metamaterial absorber integrated with graphene is presented for high-performance biosensing applications. The structure is composed of four concentric octagonal rings, where two are metallic and two are graphene-based, supported on a SiO2 su...
