论文摘要
当由两个均质介电伴侣介质的平面界面引导时，特殊的表面波可以沿孤立的方向传播，其中至少一个是各向异性的，只要合作培养基的本构参数满足某些约束。特殊的表面波通过其定位特性区别于非视觉的表面波：各向异性伴侣介质衰减中特殊表面波的场是距界面距离距离的联合线性指数函数，而衰减纯粹是指数指数的，对于非证实的表面波。如果两种伴侣介质都是各向异性的，则可以在孤立的传播方向上存在双重特殊的表面波。这两种伴侣介质中该波的衰减都由距界面距离的距离的联合线性指数函数控制。
An exceptional surface wave can propagate in an isolated direction, when guided by the planar interface of two homogeneous dielectric partnering mediums of which at least one is anisotropic, provided that the constitutive parameters of the partnering mediums satisfy certain constraints. Exceptional surface waves are distinguished from unexceptional surface waves by their localization characteristics: the fields of an exceptional surface wave in the anisotropic partnering medium decay as a combined linear-exponential function of distance from the interface, whereas the decay is purely exponential for an unexceptional surface wave. If both partnering mediums are anisotropic then a doubly exceptional surface wave can exist for an isolated propagation direction. The decay of this wave in both partnering mediums is governed by a combined linear-exponential function of distance from the interface.
