Phase-gradient metasurfaces (PGMs) constitute an efficient platform for deflection of a beam
in a desired direction. According to the generalized Snell's law, the direction of the …

Beam diffraction management with on‐demand efficiency over compact devices is important
in various applications, such as communications, spectroscopy, wireless power transfer, and …

Coupled resonances in non‐Hermitian systems can lead to exotic optical features, such as
bound states in the continuum (BICs) and exceptional points (EPs), which have been …

In recent years, metasurfaces have shown extremely powerful abilities for manipulation of
electromagnetic waves. However, the local electromagnetic response of conventional …

We theoretically formulate and experimentally demonstrate an analytical formalism for
designing printed circuit board (PCB) metagratings (MGs), exercising individual control over …

Metagratings have recently shown promising features for wavefront manipulation,
overcoming the efficiency limitations of gradient metasurfaces and their demanding …

Realizing continuous sweeping of perfect anomalous reflection in a wide angular range has
become a technical challenge. This challenge cannot be overcome by the conventional …

We report that metamaterial-inspired one-dimensional gratings (or metagratings) can be
used to control nonpropagating diffraction orders as well as propagating ones. By accurate …

Fresnel reflection has been known for centuries to fundamentally impede efficient
transmittance across planar interfaces, especially at grazing incidence. In this work, the …

As opposed to metasurfaces, metagratings represent themselves sparse arrangements of
scatterers. Established rigorous analytical models allow metagratings to overcome …
