A Dyakonov–Voigt wave (also known as DV wave and Dyakonov–Voigt surface wave) is a distinctive type of surface
A surface, as the term is most generally used, is the outermost or uppermost layer of a physical object or space. It is the portion or region of the object that can first be perceived by an observer using the senses of sight and touch, and is ...

In physics, electromagnetism is an interaction that occurs between particles with electric charge. It is the second-strongest of the four fundamental interactions, after the strong force, and it is the dominant force in the interactions o ...

. Its discoverers found that the wave is produced at the specific interface between natural or synthetic crystals and another material, such as water or oil. Such DV waves were found to travel in a single direction, and decay as they moved away from the interface. Other types of such surface waves, like 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. Unlik ...
(DSWs), travel in multiple directions, and decay more quickly. DV waves decay as "the product of a linear and an exponential function of the distance from the interface in the anisotropic medium," but the fields of the Dyakonov surface waves decay "only exponentially in the anisotropic medium". Research co-leader Tom Mackay noted: "Dyakonov–Voigt waves represent a step forward in our understanding of how light interacts with complex materials, and offer opportunities for a range of technological advancements." Applications of the newly found waves may include biosensor improvements for blood sample screening, and fiber optic circuit developments, to permit a better transfer of data.
This wave is now classified as an exceptional surface wave.
