Broadband Adjustable Terahertz Absorption in Series Asymmetric Oval-Shaped Graphene Pattern
We propose a broadband adjustable graphene absorber in terahertz regime. A prototype is designed to verify the terahertz absorption characteristics by a periodic array layer of series asymmetric oval-shaped graphene patterns on polyimide and bottom layer of metal plate. The absorber with 92% absorpt...
