title: Discrete plasmonic Talbot effect in subwavelength metal waveguide arrays.
abstract: Discrete plasmonic Talbot effect in the subwavelength metal waveguide arrays (SMWAS) is theoretically analyzed and numerically simulated. Based on the finite-difference time-domain technique, we discuss the influence of the structural parameters on the Talbot distance. By carefully choosing the geometry parameters, the Talbot distance decreases to about one third of the incident wavelength. The numerical simulation results agree with the theory of the discrete Talbot effect in the SMWAS.
