### Abstract

Dyakonov-Voigt (DV) surface waves guided by the planar interface of (i) material A, which is a uniaxial dielectric material specified by a relative permittivity dyadic with eigenvalues epsilon(s)(A) and epsilon(t)(A), and (ii) material B, which is an isotropic dielectric material with relative permittivity epsilon(B), are numerically investigated by solving the corresponding canonical boundary-value problem. The two partnering materials were generally dissipative, with the optic axis of material A being inclined at the angle chi is an element of [0 degrees, 90 degrees] relative to the interface plane. No solutions of the dispersion equation for DV surface waves exist when chi = 90 degrees. Also, no solutions exist for chi is an element of (0 degrees, 90 degrees), when both partnering materials are nondissipative. For chi is an element of [0 degrees, 90 degrees), the degree of dissipation of material A has a profound effect on the phase speeds, propagation lengths, and penetration depths of the DV surface waves. For mid-range values of chi, DV surface waves with negative phase velocities were found. For fixed values of epsilon(s)(A) and epsilon(t)(A) in the upper-half-complex plane, DV surface-wave propagation is only possible for large values of chi when vertical bar epsilon(B)vertical bar is very small.
