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 …

Nanoplasmonics is one of the most important growth areas of this century. It is part of nano-
optics and nanophotonics and deals with oscillations of electrons in metallic nanoparticles …

This Colloquium analyzes the interaction of light with two-dimensional periodic arrays of
particles and holes. The enhanced optical transmission observed in the latter and the …

We study the optical properties of subwavelength metallic waveguides made of nanoscale
apertures in a metal. We develop analytical expressions for the fundamental optical modes …

We report the enhanced transmission of electromagnetic waves through a single
subwavelength aperture by using a split-ring resonator (SRR) at microwave frequencies. By …

We observed that when subwavelength-sized holes in an optically opaque metal film are
completely covered by opaque metal disks larger than the holes, the light transmission …

We review the interaction of laser light with a single plasmonic nanostructure. Until recently,
the extremely weak optical response of a single nanostructure had only allowed …

Enhanced extraordinary optical transmission (EOT) is generated by a gold hole array with a
concentric hemisphere in the terahertz (THz) region. By introducing hemispherical particles …

The extraordinary optical transmission (EOT) of sub-wavelength nanohole array is
significantly enhanced through introducing nanoparticles, including nanospheres and …
