چکیده انگلیسی
Scattering of surface plasmon polaritons (SPP's) by small ellipsoid particles placed near a dielectric-metal interface is theoretically considered. Using the Green's function formalism and the dipole approximation, we consider the differential and total scattering cross-sections associated with the SPP-to-SPP scattering as well as with the SPP scattering into waves propagating away from the interface, analyzing the influence of system parameters. As an example, scattering cross-sections of differently shaped gold spheroid particles placed near an air-gold interface are evaluated at the light wavelength of 800Â nm. It is shown that the differential and total cross-sections depend strongly upon the particle-to-surface distance, the ratio between the major and minor axes and their orientation with respect to both the interface and the direction of SPP incidence. Implications of the obtained results to the design of SPP micro-optical components are also discussed.
