Gap surface plasmon
text:
A gap surface plasmon is a guided electromagnetic wave which propagates in a transparent medium located between two extremely close metallic regions. Propagating in a gap between metals forces light to propagate partially inside the metallic regions, causing the gap plasmon to slow down. The velocity of the gap-plasmon can be modulated by changing the thickness of the gap even by a few nanometers. A gap-plasmon is a guided mode, a solution of Maxwell's equations without source. It is the form un
