Transient Coupling of Electromagnetic Radiation To Surface Plasmons in Solid-State Structures With Time-Varying Plasma Density

Surface electromagnetic waves propagate along the interface between two media and exponentially decay with distance from the interface. The simplest interface that can guide surface waves is the boundary of a plasma or plasma-like material such as metal or a semiconductor. In this case, the surface waves are called surface plasmon polaritons or, simply, surface plasmons.
