A method for detecting Dyakonov surface waves at an interface of two anisotropic media

Abstract

The possibility of excitation and detection of Dyakonov surface waves at the interface of two identical homogeneous anisotropic media by means of the effect of polarization conversion in reflection is investigated theoretically. Excitation of the Dyakonov wave is uniquely related to a peculiarity in the reflection coefficient near a certain incidence angle determined only by parameters of the medium. The largest effect of conversion is achieved for the crystal plane exhibiting the largest difference of refractive indices.
