论文摘要
我们从理论上研究了Dyakonov表面波导模式，该模式沿着两个单轴介电介质之间的平面条带界面波导传播。我们证明，由于一维电磁限制，Dyakonov表面波导模式可以在无限界面上经典的Dyakonov表面波禁止的方向上传播。我们表明，这种情况类似于波导效应，并制定了存在Dyakonov表面波导模式的共振条件。我们证明了这种不损失的模式的传播是可能的。我们还考虑了二维限制的情况，其中两个各向异性电介质之间的界面在两个正交方向上都有界定。我们表明，这种结构支持Dyakonov表面腔模式。通过与麦克斯韦方程的全波解决方案进行比较，可以证实分析结果。我们认为，我们的作品为各向异性媒体的表面波领域的新见解铺平了道路。
We theoretically study Dyakonov surface waveguide modes that propagate along the planar strip interfacial waveguide between two uniaxial dielectrics. We demonstrate that due to the one-dimensional electromagnetic confinement, Dyakonov surface waveguide modes can propagate in the directions that are forbidden for the classical Dyakonov surface waves at the infinite interface. We show that this situation is similar to a waveguide effect and formulate the resonance conditions at which Dyakonov surface waveguide modes exist. We demonstrate that the propagation of such modes without losses is possible. We also consider a case of two-dimensional confinement, where the interface between two anisotropic dielectrics is bounded in both orthogonal directions. We show that such a structure supports Dyakonov surface cavity modes. Analytical results are confirmed by comparing with full-wave solutions of Maxwell's equations. We believe that our work paves the way towards new insights in the field of surface waves in anisotropic media.
