Multifunctional and dynamically tunable coherent perfect absorber based on InSb and graphene metasurface

Multifunctional and dynamically tunable coherent perfect absorber based on InSb and graphene metasurface

We propose a temperature-tunable and dual-broadband switchable coherent perfect absorber (CPA) composed of an annulus-disk-shaped InSb pattern and a complementary graphene layer. By controlling the Fermi level of graphene, the temperature of InSb, or the relative phase of incident beams, the working...
