The far-field reflectivity of metallic nanowire arrays designed to show strong surface-plasmon-polariton (SPP) resonances is studied numerically. The results of calculations in time and frequency space as well as the results of semi-analytic theories using different approximative boundary conditions at the metal surfaces are evaluated and compared. Good agreement between all different methods is obtained in most cases. The SPP-related features are superimposed on a strongly varying background. Combining FDTD simulations, finite element results, and semi-analytical calculations, the microscopic origin of the background contribution is identified. Resonant transmission through sub-wavelength slits leads to pronounced oscillations in the far-field reflectivity as a function of the height of the nanowires.

ABSTRACTWe model the operation of a micro-optical interferometer for surface plasmon polaritons (SPPs) that comprises an SPP beam-splitter formed by equivalent scatterers lined up and equally spaced. The numerical calculations are carried out by using a vector dipolar model for multiple SPP scattering. The SPP beam-splitter is simulated for different angles of the incident SPP beam, radii of the particles, and inter-particle distances in order to find a suitable configuration for realization of a 3dB SPP beam-splitter. The results obtained are in good agreement with experimental data available in the literature. The feasibility of fabricating an interferometer is thereby corroborated and the calculated intensity maps are found rather similar to those experimentally reported.

Dipolar Model

Using a vectorial dipolar model for multiple surface plasmon-polariton (SPP) scattering, we investigate propagation and elastic (in-plane) scattering of SPP's excited in the wavelength range of 543–633nm at random nanostructured gold surfaces. The model makes use of a composed analytic Green dyadic which takes into account near- and far-field regions, with the latter being approximated by the part describing the scattering via excitation of SPP. Simultaneous SPP excitation and in-plane propagation inside square-random arrays of nanoparticles were observed with different density of particles, demonstrating the feasibility of the suggested approach. The composed Green dyadic represents an improvement of previous SPP simulations for random nanoparticles arrays since it permits SPP scattering simulations for more realistic systems with relatively large number of close, or even in contact, nanoparticles. Our results suggest that this numerical approach is quite promising for the quantitative description of light-SPP coupling and associated processes such as weak and strong SPP localization.
