Advanced Functional Materials, EarlyView.This work presents a rate‐adaptive site transformation strategy in Ag‑ethylenediamine intercalated Co9S8, which not only enables parallel water dissociation and H* adsorption, but also allows the catalyst to provide more active sites under high demand, removing a major bottleneck. The catalyst achieves a record current density of 4.2 A cm−2@2.0 V, with

We present simulations and measurements of surface-wave waveguides (SWGs) for guiding surface waves (SWs) along a constrained path. In its simplest form, the SWG is a two-dimensional analog to a dielectric waveguide where a low-index material surrounds a high-index material.

Abstract A theoretical investigation has been made of surface spin waves localized at a (001) surface of a ferromagnetic simple cubic lattice with nearest and next-nearest neighbor exchange interactions. The excitations spectrum for the surface spin waves has been obtained and compared with that for bulk spin waves.

Nonlocal Surface-Wave Solitons
Physical Review Letters, 2007We demonstrate, experimentally and theoretically, surface-wave solitons occurring at the interface between a dielectric medium (air) and a nonlinear material with a very long-range nonlocal response. These surface solitons are always attracted toward the surface, and unlike their Kerr-like counterparts, they do not exhibit a power threshold.

Surface acoustic wave resonators
European Transactions on Telecommunications, 1991AbstractSurface Acoustic Wave (SAW) resonators are implemented by creating a planar resonant cavity, delimited by two distributed, rather than concentrated, mirrors, consisting of arrays of reflecting metal strips. SAW resonators permit to achieve higher frequencies than their bulk‐wave acoustic counterparts with comparable spectral purity and very ...

A laser beam propagating in a photorefractive crystal generates a refractive-index profile that deflects the beam to one side. This nonlinear deflection can be balanced by total internal reflection at the crystal surface to produce self-induced photorefractive surface waves. Theoretical and experimental evidence for this effect is given.

The linearized theory of surface waves leads to several mixed boundary value problems which have been investigated by various methods. As the physical background of the theory has been repeatedly discussed, it will suffice to deal here mainly with the mathematical aspect of the question.
