Journal ArticleDOI
Two-Dimensional Edge Detection by Guided Mode Resonant Metasurface
TL;DR: In this article, a new approach to perform edge detection is presented using an all-dielectric complimentary metal-oxide-semiconductor compatible metasurface, which is based on the guided-mode resonance, which provides a high quality factor resonance to make the edge detection experimentally realizable.
Journal ArticleDOI
Deriving Surface Impedance for 2-D Arrays of Graphene Patches Using a Variational Method
TL;DR: In this paper, the fundamental resonant mode of a graphene patch was extracted using a variational method using 2-D eigenvalue problem obtained from the integral equation governing the surface current on graphene patterns under quasi-static approximation.
Journal ArticleDOI
Terahertz Quarter Wave-Plate Metasurface Polarizer Based on Arrays of Graphene Ribbons
TL;DR: In this paper, a novel graphene-dielectric-based metasurface for manipulating the polarization of the incident light in the terahertz regime is proposed, which consists of two orthogonally oriented periodic array of graphene ribbons.
Journal ArticleDOI
Tunable leaky-wave radiation by graphene-covered corrugated surfaces.
TL;DR: A graphene-covered subwavelength metallic grating where the Fermi level of graphene is sinusoidally modulated as a leaky-wave antenna at terahertz frequencies can convert spoof surface plasmon guided waves to free-space radiation due to the tunability of graphene.
Journal ArticleDOI
Tunable polarization converter based on one-dimensional graphene metasurfaces
TL;DR: In this paper, a new metasurface structure for controlling the polarization of light by leveraging a well-harmonized combination of graphene and dielectric was introduced, which is composed of an array of rectangular pillars laterally sandwiched by ribbons of graphene.
