### 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 ε_{A} ^{s} and ε_{A} ^{t} , and (ii) material B, which is an isotropic dielectric material with relative permittivity ε_{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 χ ∈ [0^{◦}, 90^{◦}] relative to the interface plane. No solutions of the dispersion equation for DV surface waves exist when χ = 90^{◦}. Also, no solutions exist for χ ∈ (0^{◦}, 90^{◦}), when both partnering materials are nondissipative. For χ ∈ [0^{◦}, 90^{◦}), 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 χ, DV surface waves with negative phase velocities were found. For fixed values of ε_{A} ^{s} and ε_{A} ^{t} in the upper-half-complex plane, DV surface-wave propagation is only possible for large values of χ when |ε_{B}| is very small.

N2 - 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 εA s and εA t , and (ii) material B, which is an isotropic dielectric material with relative permittivity εB, 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 χ ∈ [0◦, 90◦] relative to the interface plane. No solutions of the dispersion equation for DV surface waves exist when χ = 90◦. Also, no solutions exist for χ ∈ (0◦, 90◦), when both partnering materials are nondissipative. For χ ∈ [0◦, 90◦), 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 χ, DV surface waves with negative phase velocities were found. For fixed values of εA s and εA t in the upper-half-complex plane, DV surface-wave propagation is only possible for large values of χ when |εB| is very small.
