The purpose of this work is to investigate theoretically the characteristics of confined electromagnetic modes propagating along the interfaces of a multilayer device. This one dimensional (ID) sensor is formed by stacking a left-handed material (LHM) layer between a SiCt₂-glass prism and a dielectric gap layer in contact with gold (Au). The results indicate that the total thickness of the LHM layer and dielectric gap, in optimum conditions, give the ability of tuning significantly the characteristics of the resonant modes correlated to surface plasmons (SPs) propagation along the interfaces of the designed device. By considering two arrangements between LHM and Au, two opposite resonant behaviors observed in p-reflectance spectra are analyzed in the angular interrogation mode and discussed thoroughly.

LHM介电间隙多层结构中表面等离激元的耦合分析

这项工作的目的是从理论上研究沿多层器件界面传播的受限电磁模式的特性。通过在SiCt ₂玻璃棱镜和与金（Au）接触的介电间隙层之间堆叠左手材料（LHM）层来形成此一维（ID）传感器。结果表明，在最佳条件下，LHM层的总厚度和介电间隙可显着调节与沿设计的器件界面传播的表面等离振子（SP）相关的谐振模式的特性。通过考虑LHM和Au之间的两种排列，在角询问模式下分析了在p反射光谱中观察到的两个相反的共振行为，并进行了深入讨论。
