TL;DR: In this article, the Berry curvature arising from the transversality of electromagnetic waves in a homogeneous medium is exploited to achieve topologically protected photonic surface states robust against disorder on all length scales.

TL;DR: The optical spin-Hall effect (OSHE) as mentioned in this paper is a spin-dependent transportation phenomenon of light as an analogy to its counterpart in condensed matter physics, which has recently attracted enormous interest due to the development of metamaterials and metasurfaces, which can provide tailor-made control of the light-matter interaction and spin-orbit interaction.

TL;DR: This work proposes and experimentally demonstrate source illusion devices to manipulate flexural waves using metasurfaces for shifting, transforming, and splitting a point source with agreement from numerical simulations and the Huygens-Fresnel theory.

TL;DR: A new research direction of software‐defined metAsurfaces is described, which attempts to push metasurfaces toward unprecedented levels of functionality by harnessing the opportunities offered by their software interface as well as their inter‐ and intranetwork connectivity and establish them in real‐world applications.

TL;DR: Here, an alternative approach for constructing metamaterials with extreme dispersion is demonstrated by simply coiling up space with curled channels, leading to a clear demonstration of negative refraction from an acoustic meetamaterial with airborne sound.
