title: Subwavelength diffraction control and self-imaging in curved plasmonic waveguide arrays.
abstract: We study subwavelength light propagation in arrays of coupled metal-dielectric waveguides with a periodically curved axis and show analytically and numerically that subwavelength diffraction management, including self-imaging effects, can be achieved by a suitable engineering of the bending geometry.
