“…The existence of multiple DT branch solutions -which is consistent with theoretical [8,9,[13][14][15], and experimental [16,17] studies of DT surface waves supported by the planar interface of a homogeneous isotropic material and a periodically-nonhomogeneous anisotropic material -is a feature that could be usefully exploited in optical sensing applications [12], for example.…”

“…All previous works on DT surface waves [8,9,[13][14][15], including experimental observations [16,17], have focused on the planar interface of a homogeneous isotropic material and a periodically nonhomogeneous anisotropic material. In contrast, here we consider the planar interface of a homogeneous anisotropic material and a periodically nonhomogeneous isotropic material.…”

The propagation of Dyakonov-Tamm (DT) surface waves guided by the planar interface of two nondissipative materials A and B was investigated theoretically and numerically, via the corresponding canonical boundary-value problem. Material A is a homogeneous uniaxial dielectric material whose optic axis lies at an angle χ relative to the interface plane. Material B is an isotropic dielectric material that is periodically nonhomogeneous in the direction normal to the interface. The special case was considered in which the propagation matrix for material A is non-diagonalizable because the corresponding surface wave -named the Dyakonov-Tamm-Voigt (DTV) surface wave -has unusual localization characteristics. The decay of the DTV surface wave is given by the product of a linear function and an exponential function of distance from the interface in material A; in contrast, the fields of conventional DT surface waves decay only exponentially with distance from the interface. Numerical studies revealed that multiple DT surface waves can exist for a fixed propagation direction in the interface plane, depending upon the constitutive parameters of materials A and B. When regarded as functions of the angle of propagation in the interface plane, the multiple DT surface-wave solutions can be organized as continuous branches. A larger number of DT solution branches exist when the degree of anisotropy of material A is greater. If χ = 0 • then a solitary DTV solution exists for a unique propagation direction on each DT branch solution. If χ > 0 • , then no DTV solutions exist. As the degree of nonhomogeneity of material B decreases, the number of DT solution branches decreases. For most propagation directions in the interface plane, no solutions exist in the limiting case wherein the degree of nonhomogeneity approaches zero; but one solution persists provided that the direction of propagation falls within the angular existence domain of the corresponding Dyakonov surface wave.

“…Such materials may be exploited in subwavelength imaging [19][20][21], for radiative thermal energy transfer [22,23], as analogues of curved spacetime [24,25], and for diffraction gratings capable of directing light into a large number of refraction channels [26], for example. Also, surface-wave propagation supported by hyperbolic materials has attracted the recent attention of both theorists and experimentalists [27][28][29][30][31][32][33][34][35][36][37].…”

A numerical investigation was undertaken to elucidate the propagation of electromagnetic surface waves guided by the planar interface of two temperature-sensitive materials. One partnering material was chosen to be isotropic and the other to be anisotropic. Both partnering materials were engineered composite materials, based on the temperature-sensitive semiconductor InSb. At low temperatures the anisotropic partnering material is a non-hyperbolic uniaxial material; as the temperature is raised this material becomes a hyperbolic uniaxial material. At low temperatures, a solitary Dyakonov wave propagates along any specific direction in a range of directions parallel to the planar interface. At high temperatures, up to three different surface waves can propagate in certain directions parallel to the planar interface; one of these surface waves propagates with negative phase velocity (NPV). At a fixed temperature, the range of directions for NPV propagation decreases uniformly in extent as the volume fraction of InSb in the isotropic partnering material decreases. At a fixed volume fraction of InSb in the isotropic partnering material, the angular range for NPV propagation varies substantially as the temperature varies.

“…При этом анализировались лишь некоторые частные случаи границ раздела двуосных кристаллов при относительно простых пространственных ориентациях их оптических осей. Кроме того, в литературе изучались и другие разновидности волн Дьяконова, существование которых возможно на границах раздела других типов веществ, таких, как гиперболические, хиральные и бианизотропные материалы [16][17][18][19], а также возникающих в ограниченных средах [20][21][22][23].…”

A general approach to analysis of Dyakonov surface waves at the interfaces of anisotropic biaxial crystals is proposed, taking into account arbitrary spatial orientation of the media tensors principal axes. This approach is based on the operator representation of macroscopic Maxwell equations corresponding to the quantum-mechanical equations for photon states in an inhomogeneous anisotropic media. Surface wave dispersion law is investigated in the most general case. It is established that the interface eigenmode dispersion is closely related to the dispersion of bulk waves in the partnering media, which is a specific feature of Dyakonov waves. The electromagnetic field spatial distribution is investigated in the direction orthogonal to the boundary plane. The surface wave angular existence domain is determined. It’s dependencies on the rotation angles of the media optical axes are studied as well.
