We investigate numerically the possibility of simultaneous surface plasmon-polariton (SPP) excitation and in-plane manipulation by using arrays of nanoparticles. The SPP excitation followed by refraction, focusing and waveguiding of SPP waves is simulated with nanoparticle arrays of different shapes, demonstrating the feasibility of the suggested approach. The calculations are based in a relative simple vectorial dipolar model for multiple SPP scattering [T. Søndergaard and S.I.
