“…Very recently, a practically important case of Dyakonov-like surface waves in finite-size resonator structures has been studied for cylindrical waveguides [34,35] as well as for flat interfacial strip waveguides [36,37]. It has been demonstrated that due to a non-zero curvature of cylindrical waveguides, Dyakonov surface waveguide modes (DSWMs) in them inevitably have radiative losses.…”

We report the prediction of a new type of Dyakonov surface waves that propagate along the flat strip of the interface between two dielectrics with negative anisotropy. It is shown that the surface waves condition is satisfied for negatively anisotropic dielectrics due to specific boundaries of the strip waveguide confined between two metallic plates. Such modes are studied by the perturbation theory in the approximation of weak anisotropy. The existence of Dyakonov surface waves in negative uniaxial crystals motivates us to reconsider the list of materials suitable for their practical implementation. We believe that this work opens a new unexplored research area in the field of surface waves.

“…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.

“…In our recent works [2,3], we theoretically study DSWs that propagate along a flat strip of the interface between two uniaxial dielectrics bounded on both sides by air or metal. We show that, due to the one-dimensional electromagnetic confinement, DSWs can propagate in directions forbidden for classical DSWs existing at an infinite interface.…”
