Two Dyakonov-Voigt surface waves guided by a biaxial-isotropic dielectric interface. [PDF]

Sci Rep, 2020
AbstractElectromagnetic surface waves guided by the planar interface of an orthorhombic dielectric material and an isotropic dielectric material were analyzed theoretically and numerically. Both naturally occurring minerals (crocoite, tellurite, and cerussite) and engineered materials were considered as the orthorhombic partnering material. In addition

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).

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 ...

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.

Dyakonov-like waveguide modes in an interfacial strip waveguide

, 2020
We study Dyakonov surface waveguide modes in a waveguide represented by an interface of two anisotropic media confined between two air half-spaces. We analyze such modes in terms of perturbation theory in the approximation of weak anisotropy.

Dyakonov Surface Waves at the Boundary of Anisotropic Biaxial Crystals

Technical Physics, 2022
A general approach to analysis of Dyakonov surface waves at the interfaces of anisotropic biaxial crystals is proposed, taking into account arbitrary spatial orientation of the media tensors principal axes. This approach is based on the operator representation of macroscopic Maxwell equations corresponding to the quantum-mechanical equations for ...

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.

Surface Waves Everywhere

, 2015
International audienceThis will be an easy review of all kinds of surface waves, i.e.waves existing specifically at interfaces between media that are different in some respect: − water waves− acoustic waves− plasma waves (or surface polaritons)− surface

Charge Generation and Recombination Pathways in All‐Polymer Bulk Heterojunction Solar Cells

Advanced Functional Materials, Volume 36, Issue 69, 27 August 2026.
Multimodal spectroscopy and device analysis reveal how field‐dependent charge generation, transport limitations, and non‐geminate recombination govern performance losses in all polymer solar cells. The results identify the key processes controlling charge extraction and recombination, providing insights for the design of more efficient all‐polymer ...

Spin Dynamics of Excitons and Carriers in Mixed‐Cation MAxFA1–xPbI3 Perovskite Crystals: Alloy Fluctuations Probed by Optical Orientation

Advanced Physics Research, Volume 5, Issue 7, July 2026.
The impact of alloy fluctuations on the spin dynamics of mixed‐cation MAxFA1‐xPbI3 perovskite single crystals is studied experimentally by means of polarized time‐resolved photoluminescence. The high optical orientation degree, reaching 80% for x = 0.1 and 0.8, displays a minimum of 60% for x = 0.4.
