Exciting a p-polarized surface plasmon in graphene
In order to excite surface plasmon polaritons in a resonant manner, one can use electron bombardment or incident light beam (visible and infrared are typical). The incoming beam has to match its momentum to that of the plasmon. In the case of p-polarized light (polarization occurs parallel to the plane of … See more Surface plasmon resonance (SPR) is a phenomenon that occurs where electrons in a thin metal sheet become excited by light that is directed to the sheet with a particular angle of incidence, and then travel parallel to the … See more Surface plasmons have been used to enhance the surface sensitivity of several spectroscopic measurements including fluorescence See more Recently, there has been an interest in magnetic surface plasmons.
