| 摘要: |
| 针对存在于半无限左手材料表面上的表面等离子体激元,研究其p型极化时的色散关系;通过棱镜耦合得到衰减全反射谱,论证实验上观察表面等离子体激元的可能性;分析各种参数对实验观察p极化表面等离子体激元的影响,发现不同的参数对表面等离子体激元与隐失波的共振频率及共振强度均有着不同影响。 |

| Abstract: |
| The dispersion relations of surface plasmon polaritons which are p-polarized and exist at the interface between a semi-innite left-handed medium and dielectric are studied.Using the prism coupling mechanism, we obtain the attenuated total reflection spectra, which demonstrates the possibility of SPPs in experimental observation;Then, we focus on the analysis of various parameters on experimental observation of p-polarization SPPs.It is found that different parameter has different effect on resonance frequency and strength between SPPs and evanescent wave. |
| Key words: surface plasmon polaritons(SPPs) attenuated total reflection(ATR) left-handed meterial evanescent wave |
