Abstract
A technique that allows one to control the elastic scattering of surface plasmon polaritons (SPP's), i.e., the SPP scattering in the surface plane, by fabricating a specially configured set of individual microscatterers is presented. Various microcomponents for two-dimensional optics of SPP's such as differently oriented micromirrors, microcavities, and a corner square micromirror, are demonstrated. SPP field distributions at single-mode microcavities exhibit spatially localized (within ) intensity enhancement by up to times.
