摘要
研究了非局域效应情况下,表面等离子体激元在以各向异性材料为衬底的纳米层状结构中的传播特性。详细推导了表面等离子体激元在各向异性纳米层状结构中的色散关系式,并通过数值计算,研究了对称与反对称两种不同模式下传播长度随结构和材料等参数的变化关系。
Taking into consideration the nonlocal effect,we investigated the propagation properties of surface plasmon polartions in anisotropic nanostructure. We derived the dispersion relation of surface plasmon polartions in anisotropic nanostructure. Based on the numerical calculation, the dependence of propagation length on the structure and material parameters in symmetric and antisymmetric modes was discussed in detail.
