Abstract
In this paper, we have developed a multi-band graphene-based anisotropic metamaterial absorber. The absorber comprises a square resonator with three apertures aligned with a finite ribbon resonator array, operating in the terahertz (THz) frequency range. It exhibits up to eight absorption bands in transverse magnetic (TM) mode and four absorption bands in transverse electric (TE) mode. In TM mode, the absorption reaches 99.92%. In TE mode, the absorption reaches 96.55%. The absorber demonstrates a maximum linear dichroism (LD) of 92%. This proposed device holds promise for applications in future terahertz systems requiring multitasking capabilities.
