Abstract
Realistic finite-difference time-domain simulations are carried to learn how to understand and control localized surface plasmons (LSP's) and traveling surface plasmon polaritons (SPP's) in metallic nanostructures. We show how to control the spatio-temporal behavior of LSP hot spots in cone-shaped metal nanoparticles. We discuss how to intensify and lengthen SPP's in thin metallic films. Finally, we discuss the relative roles of LSP's and SPP's in thin metal films with nanoscale holes and slits.
