We present a novel type of Suppressed-Order Diffraction Grating (SODG). An SODG is a diffraction grating whose diffraction orders have all been suppressed except one that is selected to provide electromagnetic deflection. The proposed SODG is a transmissive grating that exhibits high-efficiency refraction-like deflection for all angles, including large angles that are generally challenging to achieve, while featuring a deeply subwavelength thickness, as required in the microwave regime. We…

Polarizing Beamsplitter Grating based on Asymmetric Slot Waveguide Scatterer

We demonstrate a novel design for grating-based polarizing beamsplitters (PBSs). The structure has a subwavelength thickness and is engineered to suppress all diffraction orders except for those of

Analysis and Design of General Printed Circuit Board Metagratings With an Equivalent Circuit Model Approach

An accurate equivalent circuit model (ECM) for general multiwire multiorder printed circuit board (PCB) metagratings (MGs) is developed and it is possible to encode multiple functions into a single device by simultaneously optimizing all relevant entries of the ECM scattering matrix.



Role of propagating modes in a double-groove grating with a +1st-order diffraction angle larger than the substrate-air critical angle.

Here we show, analytically and numerically, that in a TiO(2) double-groove grating with two different groove widths per period attached on the SiO(2) substrate, the normally incident light couples to

Susceptibility Derivation and Experimental Demonstration of Refracting Metasurfaces Without Spurious Diffraction

Refraction represents one of the most fundamental operations that may be performed by a metasurface. However, simple phase-gradient metasurface designs suffer from restricted angular deflection due

Coupled wave theory for thick hologram gratings

A coupled wave analysis is given of the Bragg diffraction of light by thick hologram gratings, which is analogous to Phariseau's treatment of acoustic gratings and to the “dynamical” theory of X-ray

Volume‐Phase Holographic Gratings and the Efficiency of Three Simple Volume‐Phase Holographic Gratings

Volume‐phase holographic (VPH) gratings show great potential as an alternative dispersing element to the classical surface‐relief (SR) gratings presently used in most astronomical spectrographs. We

We present a methodology for designing metagratings for perfect anomalous refraction, based on multilayered loaded wire arrays. In recent work, it has been shown that such structures can implement

Huygens’ metasurfaces from microwaves to optics: a review

Abstract In this article, the basic principles and the main applications of Huygens’ metasurfaces (HMSs) are reviewed from microwaves to optics. In general, HMSs comprise a thin layer of orthogonal

Metagratings: Beyond the Limits of Graded Metasurfaces for Wave Front Control.

The concept of metagratings, formed by periodic arrays of carefully tailored bianisotropic inclusions, are introduced and it is shown that they enable wave front engineering with unitary efficiency and significantly lower fabrication demands.

Large-Angle, Multifunctional Metagratings Based on Freeform Multimode Geometries.

It is shown that silicon-based metagratings capable of large-angle, multifunctional performance can be realized using inverse freeform design, and envisioned that inverse design will enable new classes of high-performance photonic systems and new strategies toward the nanoscale control of light fields.

Analytical Design of Printed Circuit Board (PCB) Metagratings for Perfect Anomalous Reflection

We present an analytical scheme for the design of realistic metagratings for wide-angle engineered reflection. These recently proposed planar structures can reflect an incident plane wave into a

Five recent metasurface concepts and applications are presented, which cover the topics of birefringent transformations, bianisotropic refraction, light emission enhancement, remote spatial processing, and nonlinear second-harmonic generation.
