Abstract:To construct photodetector and photovoltaic devices, light absorption is crucial. Herein, the absorption properties of a photonic crystal (PhC) consisting of high‐ and low‐index dielectric materials and a metamaterial defect layer are investigated. Two graphene sheets are assumed to surround the metamaterial layer. The study is theoretically investigated and numerically simulated in the gigahertz region. The metamaterial negative permittivity and permeability are assumed to follow the Drude model. The number o… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
