Graphene is a powerful 2-D matter with the capability of extraordinary transparency, and tunable conductivity employed in emerging optoelectronics devices. In this article, design an electrically graphene-based perfect terahertz absorber proposed evaluated numerically. The introduced structure composed two graphene layers sharp absorption peak band. These are combline stripline separated by ins...
