摘要:
我们研究了在二氧化硅基底中植入${\mathrm{Er}}^{3+}$离子和银纳米颗粒的光传播,这些颗粒在基底中随机且均匀分布。当它们的密度足够大时,介质可以在一定频率范围内具有负折射率,在此范围内出现以下奇异性质:增加电和磁等离子体频率,介质的透明度会增强。
英文摘要:
We consider light propagation in a silicon dioxide substrate with implanted ${\mathrm{Er}}^{3+}$ ions and silver nanoparticles that are randomly and homogeneously distributed in the substrate. When their densities are large enough, the medium can have a negative refractive index over a certain range of frequencies, within which the following exotic property ensues: increasing the electric and magnetic plasma frequencies, the medium transparency is augmented.
