Geometry and surface plasmon energy
Artikel i övriga tidskrifter, 2011
We derive a simple rule to determine surface plasmon energies, based on the geometrical prop-
erties of the surface of the metal. We apply this concept to obtain the surface plasmon energies in
wedges, corners and conical tips. The results presented here provide simple and straightforward
rules to design the energy of surface plasmons in severals situations of experimental interest such
as in plasmon wave guiding and in tip-enhanced spectroscopies.
