Abstract
On the basis of an impedance boundary condition, we study theoretically the transmission of a surface plasmon polariton incident normally on a periodic row of circular metallic or dielectric dots deposited on a planar metallic substrate. The field of the transmitted surface plasmon polaritons displays periodic self-images of this row that are separated from it by multiples of a characteristic distance. This is the analogue for surface plasmon polaritons of the Talbot effect for volume electromagnetic waves.
