论文摘要
我们研究了Dyakonov表面波导模式，该模式由两个偏置两个空气半空间之间的各向异性介质的界面表示。我们在弱各向异性近似中分析了这种模式。我们表明，与传统的dyakonov表面波相反，这些表面波与距界面距离单调衰减，而dyakonov波导模式可以使场强度的局部最大值远离界面。我们通过将它们与全波电磁模拟进行比较来确认我们的分析结果。我们认为，这项工作可以在Dyakonov表面波的研究中带来新的想法。
We study Dyakonov surface waveguide modes in a waveguide represented by an interface of two anisotropic media confined between two air half-spaces. We analyze such modes in terms of perturbation theory in the approximation of weak anisotropy. We show that in contrast to conventional Dyakonov surface waves that decay monotonically with distance from the interface, Dyakonov waveguide modes can have local maxima of the field intensity away from the interface. We confirm our analytical results by comparing them with full-wave electromagnetic simulations. We believe that this work can bring new ideas in the research of Dyakonov surface waves.
