We propose a structure of bilayer dielectric metasurfaces consisting of silicon nano-cuboids with high-quality (Q) transmittance due to the coupling effect between Fabry–Perot and Mie resonances. The synthesis of the structure is done by using a no

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

The ultrathin graphene metasurface is proposed as a mantle cloak to achieve wideband tunable scattering reduction around the spherical (three-dimensional) objects. The cloaking shell over the metallic or dielectric sphere is structured by a periodic

In this article a new method for creating mixer component in infrared and THz is suggested. Since the nonlinear property of admittance creates frequency components that do not exist in the input signal and the electrical conductivity is associated wi
