Extraordinary optical transmission (EOT) is a term that refers to electromagnetic resonances
through sets of subwavelength apertures in either a flat or a corrugated metal film, providing …

Resonators of surface plasmons are discussed in this review. Any material supporting the
excitation of surface plasmons, either by light, or by electron beams can be used for …

We demonstrate orbital angular momentum (OAM) transfer by chiral plasmonic
nanostructures designed on both sides of a thin suspended metallic membrane. We show …

Non-diffracting Bessel beams, including zero-order and high-order Bessel Beams which
carry orbital angular momentum (OAM), enable a variety of important applications in optical …

Control of light–matter interactions at the nanoscale has advanced fields such as quantum
optics, photovoltaics and telecommunications. These advances are driven by an improved …

Circular dichroism, that is, the differential absorption of a system to left and right circularly
polarized light, is one of the only techniques capable of providing morphological information …

We focus on physically analyzing the origins of the numerical aperture (NA) and the
spherical aberration of the microsphere with wavelength scale radius. We demonstrate that …

We investigate experimentally the parameter space defining, in the visible range, the far-
field diffraction properties of a single circular subwavelength aperture surrounded by …

Local distribution of the optical magnetic field is a critical parameter in developing materials
with artificially engineered optical properties. Optical magnetic field characterization in nano …

It is generally believed that when a single metallic nanowire is sufficiently small, it scatters
like a point electric dipole. We show theoretically when a metallic nanowire is placed inside …
