Simultaneous existence of amplified and attenuated Dyakonov surface waves [PDF]

Optics Communications, 2018
The propagation of Dyakonov surface waves guided by the planar interface of (i) an isotropic dielectric material and (ii) a homogenized uniaxial dielectric composite material comprising both passive and active component materials was theoretically investigated, under the assumption that the optic axis of the uniaxial partnering material lies wholly in ...

A general recipe to observe non-Abelian gauge field in metamaterials. [PDF]

Nanophotonics
Abstract Recent research on non‐Abelian phenomena has cast a new perspective on controlling light. In this work, we provide a simple and general approach to induce non‐Abelian gauge field to tremble the light beam trajectory. With in‐plane duality symmetry relaxed, our theoretical analysis finds that non‐Abelian electric field can be synthesized ...

Casimir interaction driven by hyperbolic polaritons. [PDF]

Nanophotonics
Abstract Casimir interaction is an intriguing phenomenon that is induced by electromagnetic quantum fluctuations, which dominates the interaction between microstructures at small separations and is essential for micro‐ and nano‐electromechanical systems (MEMS and NEMS).

Dyakonov surface wave resonant transmission

Optics Express, 2011
The role of Dyakonov surface waves in the transmission through structures composed of birefringent media is theoretically explored. In the case of structures using prisms, unexpected high transmission above the critical angle due to resonant excitation of Dyakonov surface waves is predicted. This transmission is produced only when TE polarized incident

Singular existence of a Dyakonov–Voigt surface wave: Proof

Results in Physics, 2021
If Dyakonov surface-wave (DSW) propagation can be guided by the planar interface of an isotropic dielectric medium and a uniaxial dielectric medium with its optic axis lying wholly in the interface plane, then a Dyakonov–Voigt surface wave can propagate in at most one direction within the angular sector for DSW propagation.

Kelvin-Mach wake in a two-dimensional Fermi sea [PDF]

, 2018
The dispersion law for plasma oscillations in a two-dimensional electron gas in the hydrodynamic approximation interpolates between $\Omega \propto \sqrt{q}$ and $\Omega \propto q$ dependences as the wave vector $q$ increases.

Substantial enlargement of angular existence range for Dyakonov-like surface waves at semi-infinite metal-dielectric superlattice [PDF]

, 2012
We investigated surface waves guided by the boundary of a semi-infinite layered metal-dielectric nanostructure cut normally to the layers and a semi-infinite dielectric material.

Controllable selective coupling of Dyakonov surface wave at liquid-crystal-based interface [PDF]

Conference on Lasers and Electro-Optics, 2020
A selective coupling behavior of Dyakonov surface wave at the liquid-crystal-based interface has been demonstrated experimentally. Such a highly directional and lossless surface wave has promising applications in two-dimensional photonic circuits and devices.
