研究了表面等离子体激元（SPP）波在金属-电介质界面上的传播特性。金属是银，介电材料是浸渍有活性染料组合的多氧化钒。取决于钒多氧化物的体积分数，可以实现SPP波的衰减或放大;衰减或放大的程度强烈地取决于温度以及温度是升高还是降低。在钒多氧化物的中间体积分数下，对于固定温度，如果温度升高，SPP波可能经历衰减，但如果温度降低，SPP波可能经历放大。
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.
