Over the last dozen years, the area of accelerating waves has made considerable advances
not only in terms of fundamentals and experimental demonstrations, but also in connection …

Self-healing of light refers to the ability of a light field to recover its structure after being
damaged by a partial obstruction placed in its propagation path. Here, we will give a …

A unique feature of non-Hermitian (NH) systems is the NH skin effect, ie, the edge
localization of an extensive number of bulk-band eigenstates in a lattice with open or semi …

Metasurfaces with subwavelength thicknesses have exhibited unconventional phenomena
in ways that could not be mimicked by traditional materials. Here we report on the analytical …

Airy beams maintain their intensity profiles over a large propagation distance without
substantial diffraction and exhibit lateral bending during propagation,,,,. This unique property …

Metamaterial Huygens' surfaces manipulate electromagnetic wavefronts without reflection. A
broadband Huygens' surface that efficiently refracts normally incident light at the …

We theoretically and experimentally investigate a helical acoustic metasurface capable of
providing a modulated sound-reflected wavefront and a continuously tunable broadband …

Spin–momentum locking, a manifestation of topological properties that governs the behavior
of surface states, was studied intensively in condensed-matter physics and optics, resulting …

In this letter, we reported the experimental observation of a photonic hook (PH)—a type of
near-field curved light generated at the output of a dielectric cuboid, featuring a broken …

Propulsive effects of light, which often remain unnoticed in our daily-life experience, manifest
themselves on spatial scales ranging from subatomic to astronomical. Light-mediated forces …
