Tunable Dyakonov surface waves in graphene-hBN hyperstructure

Optics Communications, 2021
Abstract Here we analyze the propagation of Dyakonov surface waves(DSWs) at the interface between isotropic dielectric material and graphene-hBN hyperstructure (GhH) whose physical properties and optical topological transition regions can be controlled by varying the Fermi energy level of graphene sheets via electrostatic biasing.

Terahertz Dyakonov surface waves in plasma metamaterials

Optics Letters, 2018
Metamaterials in which plasmas are included have significant properties that may not be found in ordinary metamaterials. The permittivity function of these engineered materials can be rapidly manipulated by applying external electric and magnetic field or changing the gas pressure, temperature, and collisional frequency.

Dyakonov-like surface waves in the THz regime

Photonics and Nanostructures - Fundamentals and Applications, 2016
Abstract Here we examine Dyakonov-like surface waves (DSWs) in the THz regime traveling along the plane interface between a non-conducting isotropic medium and a low-loss graphene-based uniaxial metamaterial with the optic axis (OA) oriented along with the interface.

Resonant transmission mediated by Dyakonov surface waves

2011 Conference on Lasers and Electro-Optics Europe and 12th European Quantum Electronics Conference (CLEO EUROPE/EQEC), 2011
A special type of surface wave was predicted by M. I. Dyakonov in 1988 [1]. Such waves exist under special conditions at the interface of transparent anisotropic materials, and hens they are lossless. This surface waves require at least one of the two media to be an anisotropic medium, either biaxial or positive uniaxial, and various configurations ...

Theory of grating-coupled excitation of Dyakonov surface waves

Optical Engineering, 2020
Excitation of Dyakonov surface waves guided by a plane wave incident on a columnar thin film (CTF) deposited on a surface-relief grating decorating a dielectric substrate was studied using the rigorous coupled-wave approach, when the grating plane, the plane of incidence, and the morphologically significant plane of the CTF are all different.

Dyakonov surface waves at the interface of nanocomposites with spherical and ellipsoidal inclusions

Optical and Quantum Electronics, 2019
The dispersion properties of different types of surface electromagnetic waves which are supported by the interface of two nanocomposite materials with inclusions of different shape are studied theoretically and numerically. Both nanocomposites are made of doped n-type semiconductor inclusions which are evenly distributed in a transparent dielectric ...

Dyakonov hybrid surface waves at the isotropic–biaxial media interface

Journal of the Optical Society of America A, 2015
Dyakonov surface waves (DSWs) at the interface of an isotropic dielectric material and a biaxial dielectric crystal were considered in the case in which two principal axes of the biaxial crystal lie in the plane of the interface. Both x-cut and y-cut biaxial crystals were considered, and all permittivity scalars were assumed to be real and positive.

Review of the role of dielectric anisotropy in Dyakonov surface-wave propagation

SPIE Proceedings, 2008
Surface waves (SWs) are localized waves that travel along the planar interface between two different mediums when certain dispersion relations are satisfied. If both mediums have purely dielectric constitutive properties, the characteristics of SW propagation are determined by the anisotropy of both mediums.

Dyakonov Surface Electromagnetic Waves in III‐Nitride Heterostructures

physica status solidi (b), 2018
Lossless Dyakonov surface electromagnetic waves (DWs) that may be excited at the interfaces between non‐polar III‐nitride wurtzite semiconductors and optically isotropic dielectrics are considered theoretically. Because of stringent requirements on optical properties of the dielectrics suitable for DW excitation, those of them satisfying the existence ...
