研究了在高介电常数棱镜介质附近自由电子金属表面存在的表面极化子的特性，包括棱镜介质的有限长度和表面极化子幅度的缓慢空间变化的影响。讨论了表面极化子的辐射衰减特性和通过棱镜介质气隙入射到金属表面的光的反射率角响应中的反共振特性，以及金属中的小损耗对这些特性的影响。
The characteristics of the surface polariton existing on the surface of a free electron metal in the proximity of a higher permittivity prism dielectric are investigated including the effects of the finite length of the prism dielectric and the slow spatial variation of the amplitude of the surface polariton. The radiative decay characteristics of the surface polariton and the characteristics of the antiresonance in the angular response of the reflectivity of light incident on the metal surface via the air gap from the prism dielectric are treated, and the effect of a small loss in the metal on these characteristics is also presented.
