## Contribution

It introduces a general analytical theory for Dyakonov waves in biaxial crystals, classifying different wave types and deriving their dispersion characteristics.

## Key findings

- Dyakonov waves can be divided into two distinct classes with different spatial behaviors.
- Explicit expressions for dispersion relations of Dyakonov waves are derived.
- Parameter ranges for the existence of these waves are identified.

## Abstract

We present the general analytical theory for Dyakonov surface waves at the interface of a biaxial anisotropic dielectric with an isotropic medium. We demonstrate that these surface waves can be divided into todo distinct classes, with qualitatively different spatial behavior. We obtain explicit expressions for the Dyakonov waves dispersion and the parameter range for their existence.
