The recently proposed concept of metagrating enables wavefront manipulation of electromagnetic (EM) waves with unitary efficiency and relatively simple fabrication requirements. Herein, twodimensional (2D) metagratings composed of a 2D periodic array of rectangular holes in a metallic medium are proposed for diffraction pattern control. We first present an analytical method for diffraction analysis of 2D compound metallic metagrating (a periodic metallic structure with more than one rectangular…

Analytical method for diffraction analysis and design of perfect-electric-conductor backed graphene ribbon metagratings.
TLDR
An accurate analytical method is proposed for diffraction analysis of a perfect electric conductor (PEC)-backed array of graphene ribbons and can predict the electromagnetic performance of graphene Ribbons not only in the subwavelength regime, but also for wavelengths shorter than the array constant.
Unveiling the Properties of Metagratings via a Detailed Analytical Model for Synthesis and Analysis
TLDR
Detailed analytical modelling and in-depth investigation of wide-angle reflect-mode metagrating beam splitters are presented and it is revealed that metagratings feature preferable working points, in which the sensitivity to these non-idealities is rather low.
Analytical method for the diffraction of an electromagnetic wave by subwavelength graphene ribbons
Theoretical study of arrays of graphene ribbons is currently of high interest due to its potential application in beam splitters, absorbers, and polarizers. In this paper, an analytical method is

Controlling Diffraction Patterns with Metagratings
In this study we elaborate on the recent concept of metagratings proposed in Ra'di et al. [Phys. Rev. Lett. 119, 067404 (2017)] for efficient manipulation of reflected waves. Basically, a metagrating
Huygens' metasurfaces via the equivalence principle: design and applications
We review the current trends in the design of Huygens’ metasurfaces (HMSs), which are planar arrays of balanced electric and magnetic polarizable particles (meta-atoms) of subwavelength size. We
Analytical theory of extraordinary transmission through metallic diffraction screens perforated by small holes.
TLDR
The analysis has revealed that one of the key factors behind ET is the continuous increase of excess electric energy around the holes as the frequency approaches the onset of some of the higher-order modes associated with the periodicity of the screen.
Perfect control of reflection and refraction using spatially dispersive metasurfaces
Nonuniform metasurfaces (electrically thin composite layers) can be used for shaping refracted and reflected electromagnetic waves. However, known design approaches based on the generalized
