Nondiffracting Bessel plasmons.
We report on the existence of nondiffracting Bessel surface plasmon polaritons (SPPs), advancing at either superluminal or subluminal phase velocities. These wave fields feature deep subwavelength FWHM, but are supported by high-order homogeneous SPPs of a metal/dielectric (MD) superlattice. The beam axis can be relocated to any MD interface, by interfering multiple converging SPPs with control...
متن کاملSurface plasmons and singularities.
We apply the conformal transformation technique to study systematically a variety of singular plasmonic structures, including two-dimensional sharp edges, rough surfaces, and nanocrescents. These structures are shown to exhibit two distinct features. First, different from a planar metallic surface, the surface plasmon excitations on the examined structures have a lower bound cutoff at a finite ...
متن کاملBouncing surface plasmons.
Employing an interferometric cavity ring-down technique we study the launching, propagation and reflection of surface plasmons on a smooth gold-air interface that is intersected by two parallel, sub-wavelength wide slits. Inside the low-finesse optical cavity defined by these slits the surface plasmon is observed to make multiple bounces. Our experimental data allow us to determine the surface-...

showing instead non-directional rotation at a much higher speed of rotation. The directional rotation is provoked by the chirality of the STM tip (Fig. 1c)5. In particular, the differences observed for enantiomers on electrical excitation with the same STM tip are attributed to non-identical tip–molecule interactions. The intramolecular vibrational energy redistribution from the high-energy C–H...
متن کاملHolographic Optical Elements for Holographic Stereogram Printers
A number of methods for producing holographic optical elements (HOEs) for use in projecting integral images in holographic stereogram printers are presented, with emphasis on application to Ultragram format one-step stereograms. Creation of HOEs to replace standard diffusion screens and enhance stereogram printer imaging properties and efficiency is discussed. Monolithic and integral holographi...
