摘要：
研究了在金属与介电材料的平面界面处，具有强温度依赖性本构特性的介电材料中表面等离子体极化波（SPP）的传播。金属为银，介电材料为浸渍活性染料混合物的多氧化钒。根据多氧化钒的体积分数，可实现SPP波的衰减或放大；衰减或放大的程度强烈依赖于温度以及温度处于上升或下降状态。在多氧化钒的中间体积分数下，对于固定温度，若温度上升，SPP波可能经历衰减，但若温度下降，则可能经历放大。
英文摘要：
The propagation of surface-plasmon-polariton (SPP) waves at the planar interface of a metal and a dielectric material was investigated for a dielectric material with strongly temperature-dependent constitutive properties. The metal was silver and the dielectric material was vanadium multioxide impregnated with a combination of active dyes. Depending upon the volume fraction of vanadium multioxide, either attenuation or amplification of the SPP waves may be achieved; the degree of attenuation or amplification is strongly dependent on both the temperature and whether the temperature is increasing or decreasing. At intermediate volume fractions of vanadium multioxide, for a fixed temperature, a SPP wave may experience attenuation if the temperature is increasing but experience amplification if the temperature is decreasing.
