Abstract

In this study, polarization detection of the incident wave with amplitude and frequency is achieved by proposed graphene-based metasurfaces for integrated optics applications. Metasurfaces consist of elliptical nanodisks of graphene as the meta-atoms. Synthesis of the metasurfaces is based on the analytical approach of the equivalent conductivity method. The elliptical nanodisks play an asymmetric meta-atom role with respect to the polarization of the incident waves. This concept is applied to design polarization selective metasurfaces. Two types of polarization-sensitive metasurfaces are designed. One of them has unique nanodisks that change the absorbance coefficient by varying the polarization of the incident wave in an absorber structure. The second one has three types of elliptical nanodisks with various dimensions and orientations that distinguish the polarization. This metasurface is used in a demultiplexing structure to select a desired wave with a specific frequency.
