We experimentally demonstrated planar lenses based on nanoscale slit arrays in a metallic film. Electromagnetic simulations of lens designs and confocal measurements on manufactured structures show excellent agreement, but deviate from simple theory.
The optical properties of nanoscale apertures in optically thick metallic films have been intensely researched in the past years due to their fundamental importance in near-field optics. Here, we show that the entire dispersion behavior of a plasmonic structure with coaxial cross-section i.e., formed by a dielectric ring between a metallic core and a metallic cladding, is well-approximated by a simple...
We analyze propagating plasmonic modes in deep-subwavelength coaxial metallic waveguides with a hollow core. Such modes couple to plane waves and exhibit much larger cut-off wavelengths than the TE11-mode in a conventional coaxial waveguide.
