摘要

大多数超材料表现出明显的各向异性，这对于理解其优越的光学性能至关重要，特别是当它们被集成到等离子波导结构中时。本文解析求解了填充各向异性层状超材料的狭缝等离子波导的色散关系，揭示了在狭缝厚度消失的极限下，它支持两种具有较长传播长度的模式。我们根据它们的物理来源对它们进行分类，并研究了它们的色散特性随材料参数的变化。

Plasmonic Modes of Metamaterial-Based Slot Waveguides

Most metamaterials exhibit pronounced anisotropic properties that are crucial for the understanding of their superior optical behavior, especially when they are integrated into the structure of a plasmonic waveguide. In this paper, we analytically solve the dispersion relation for a slot plasmonic waveguide filled with an anisotropic-stratified metamaterial and reveal that it supports two modes featuring relatively long propagation lengths in the limit of vanishing slot thickness. We classify these modes according to their physical origin and study the variation of their dispersion properties with material parameters.
