Metasurfaces are ultrathin metamaterials consisting of planar electromagnetic (EM)
microstructures (eg, meta-atoms) with pre-determined EM responses arranged in specific …

This review provides a perspective on the recent developments in the transmission of light
through subwavelength apertures in metal films. The main focus is on the phenomenon of …

Collective electronic excitations at metal surfaces are well known to play a key role in a wide
spectrum of science, ranging from physics and materials science to biology. Here we focus …

We show that a single rectangular hole in a metallic film exhibits transmission resonances
that appear near the cutoff wavelength of the hole waveguide. For light polarized with the …

The effect of the aspect ratio of rectangular holes on the transmissivity of periodic arrays of
subwavelength holes in optically thick metal films is investigated. The transmissivity is found …

Resonantly enhanced light transmission through periodic subwavelength aperture arrays
perforated in metallic films has generated significant interest because of potential …

Extraordinary optical transmission through an array of holes in a metal film was reported by
Ebbesen and coworkers in 1998. Since that work there has been abundant research activity …

We present the experimental demonstration of what are to our knowledge the first two-
dimensional planar plasmonic lenses formed by an array of spatially varying cross-shaped …

A theory is presented to describe the optical transmission through a rectangular hole in a
real metal film. The previous theory of the transmission through a rectangular hole in a …

Abstract Development of terahertz (THz) sources, detectors, and optical components has
been an active area of research across the globe. The interest in THz optoelectronics is …
