论文摘要
通常，一种三材结构，其中包含一个足够薄的金属膜，该膜在两个均质的介电材料之间插在两种均匀的介电材料之间，指南化合物等离子体 - 果龙（CPP）波，为金属膜两侧的磁场呈指数型，距离最近的金属/介电/介电界面的距离。但是，如果一种介电材料是各向异性的，则三层材料结构可以指导特定传播方向的特殊CPP波。在各向异性介电材料占据的金属膜的一侧，特殊CPP波衰减的场是线性函数的乘积和距离最近金属/介电界面的距离的指数函数。 CPP波传播的规范边界值问题已通过数值分析和求解。因此，已经建立了单轴二型/金属/各向同性 - 射电结构的特殊CPP波的空间场曲线。
Ordinarily, a trimaterial structure comprising a sufficiently thin metal film interposed between two homogeneous dielectric materials guides compound plasmon-polariton (CPP) waves, for which the fields on both sides of the metal film decay exponentially with distance from the nearest metal/dielectric interface. However, if one of the dielectric materials is anisotropic then the trimaterial structure can guide an exceptional CPP wave for a particular propagation direction. On the side of the metal film occupied by the anisotropic dielectric material, the fields of the exceptional CPP wave decay as the product of a linear function and an exponential function of the distance from the nearest metal/dielectric interface. The canonical boundary-value problem for CPP-wave propagation has been analyzed and solved numerically; thereby, the spatial field profiles for exceptional CPP waves for a uniaxial-dielectric/metal/isotropic-dielectric structure have been established.
