The phenomena-recently named Dyakonov-Voigt could have a range of useful effects

Scientists and Engineers from the University of Edinburgh and Pennsylvania State University made the discovery by analyzing how light-which travels in the form

They found that Dyakonov-Voigt's waves are produced at a specific region-known as an interface-where the crystals meet another material, such as oil or water.

The team identified the waves' unique properties using mathematical models developed by James Clerk Maxwell , Dyakonov-Voigt waves, named after two leading scientists, as diminish as.

Dyakonov-Voigt waves, named after two leading scientists, diminish as they move away from the interface-a process called decay-and travel only in a single direction, the team found. Other types of so-called surface waves decay more quickly and travel in multiple directions.

Dr. Tom Mackay, of the University of Edinburgh's School of Mathematics, said, "Dyakonov-Voigt's waves represent a step forward in our understanding of how to make light interacting with complex materials, and offer opportunities for a range of technological advancements.

The study is published in Proceedings of the Royal Society A .
