Rectangular gold and silver nano-strips embedded in glass or water are considered as optical resonators. Their scattering cross section and field enhancements in the case of p-polarized plane-wave illumination are analyzed using a surface integral equation method. Peaks in the scattering spectra are shown to be related to the resonant excitation of forward and backward travelling short-range surface plasmon polaritons in thin metal strips. The influence of angle of incidence and strip thickness… CONTINUE READING
