研究了介质/超材料界面上的S极化表面等离子体激元，给出了它们的色散关系。利用棱镜耦合机制，得到了基于Otto位形的频率范围内的衰减全反射(ATR)谱。结果表明，在不改变耦合频率的情况下，介质层的厚度和超材料的小阻尼对耦合强度有显著影响。此外，介质的最佳厚度随着阻尼值的增大而减小，超材料的系数F也决定了耦合频率和强度。
The s-polarized surface plasmon polaritons (SPPs) at the interface between dielectric and metamaterial are studied, and the dispersion relations of SPPs are also presented. Using the prism coupling mechanism, we obtain the attenuated total reflection (ATR) spectra in the frequency regime based on the Otto configuration. It is found that the thickness of the dielectric in the configuration and the small damping of the metamaterial affect the coupling strength significantly without changing the coupling frequency. Furthermore, the optimized thickness of the dielectric decreases with a larger damping, and the coefficient F of the metamaterial also determines the coupling frequency and strength.
