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 …

The presence of tiny holes in an opaque metal film, with sizes smaller than the wavelength
of incident light, leads to a wide variety of unexpected optical properties such as strongly …

Transmission enhancements of order 1000 have been reported for subwavelength hole
arrays in metal films and attributed to surface plasmon (SP) resonance. We show that the …

Local electromagnetic field fluctuations and related enhancement of nonlinear phenomena
in metal-dielectric composites near the percolation threshold (percolation composites) have …

After reviewing the present understanding of the transmission properties of single apertures
and the enhanced transmission through hole arrays, experimental results are presented …

We demonstrate the extraordinary transmission of terahertz THz radiation through gratings
of subwavelength apertures structured in indium antimonide InSb. This transmission can be …

We have analyzed the transmission process through single subwavelength apertures
surrounded by a set of periodic grooves in optically thick Ag films. On one hand, we found …

We demonstrate optical control over the transmission of terahertz (THz) radiation through a
single subwavelength slit in an otherwise opaque silicon wafer. The addition of periodic …

In this Letter we show that the extraordinary optical transmission phenomenon found before
in 2D hole arrays is already present in a linear chain of subwavelength holes, which can be …

In this letter, a very low-profile planar horn antenna is proposed. It consists of a
subwavelength aperture placed into a" Bull's Eye" concentric periodic corrugated conducting …
