Dyakonov–Voigt wave

The Dyakonov–Voigt wave refers to a type of electromagnetic wave that propagates in a birefringent medium. This phenomenon is named after the researchers Mikhail Dyakonov and Ya. P. Voigt, who studied the behavior of waves in certain anisotropic materials. In a birefringent medium, the speed of light differs depending on the polarization state of the light and the direction of propagation.
