What Does SPP Stand For?
SPP stands for Surface Plasmon Polariton
Surface Plasmon Polariton (SPP) is a hybrid electromagnetic wave that arises at the interface between a conductive material and a dielectric, such as air or glass. It combines features of surface plasmons, which are coherent oscillations of free electrons in the metal, and optical photons in the dielectric medium. SPPs are characterized by their ability to propagate along the surface while being confined to a subwavelength scale, making them essential for applications in plasmonic devices, sensors, and enhanced light-matter interactions in nanophotonics. Their unique properties enable advancements in fields such as imaging, spectroscopy, and quantum technologies.
