Dyakonov surface waves
Dyakonov surface waves (DSWs) are surface electromagnetic waves that travel along the interface in between an isotropic and an uniaxial-birefringent medium. They were theoretically predicted in 1988 by the Russian physicist Mikhail Dyakonov. Unlike other types of acoustic and electromagnetic … See more The simplest configuration considered in Ref. 1 consists of an interface between an isotropic material with permittivity ε and a uniaxial crystal with permittivities ε0 and εe for the ordinary and the extraordinary waves respectively. … See more A widespread experimental investigation of DSW material systems and evolution of related practical devices has been largely limited by the stringent See more • Dyakonov–Voigt wave • Surface wave • Leaky mode See more WebDec 20, 2024 · Excitation of high-phase-speed Dyakonov surface waves guided by a surface-relief grating made of a uniaxial dielectric material was theoretically studied …

A Dyakonov–Voigt wave (also known as DV wave and Dyakonov–Voigt surface wave) is a distinctive type of surface electromagnetic light wave that results from a particular manipulation of crystals. It was discovered in 2024 by researchers from the University of Edinburgh and Pennsylvania State University and its unique properties were described based on models involving equations developed in the mid-1800s by mathematician and physicist James Clerk Maxwell. Its … WebIn the current paper the properties of surface plasmon polaritons as well as hybrid polarized surface electromagnetic waves at the plane interface of a porous semiconductor nanomaterial and a hypercrystal are studied theoretically and numerically. The nanomaterial, as well as the hypercrystal, is made of n-type doped indium antimonide (n-InSb ...
WebSep 4, 2024 · The researchers found that Dyakonov-Voigt surface waves are produced at a specific region — known as an interface — where the crystals meet another material, such as oil or water. Named after two leading scientists, these waves can be produced only using certain types of crystal whose optical properties depend on the direction in which ...
