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.

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.File in questo prodotto:
