表面等离激元
Surface Plasmon PolaritonsSurface Plasmon Polaritons (SPPs) are electromagnetic waves that travel along a metal-dielectric interface, bound to the interface due to the coupling of electromagnetic waves with the oscillations of free electrons at the surface. / 表面等离激元（SPP）是沿着金属-电介质界面传播的电磁波，由于电磁波与界面处自由电子振荡的耦合而束缚在界面上。
