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 terahertz (THz) spectrum is the focus of basic research in solid‐state physics, chemistry,
and materials science as well as applications in next‐generation communications, far …

The unique optical properties of metals are at the core of many areas of research and
applications, including plasmonics,,,, metamaterials,, superlensing and subdiffraction …

Unusual performances of metamaterials such as negative index of refraction, memory effect,
and cloaking originate from the resonance features of the metallic composite atom 1− 6 …

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 describe the electronic control of extraordinary terahertz transmission through
subwavelength metal hole arrays fabricated on doped semiconductor substrates. The hybrid …

We report on the observation of terahertz transparency in random arrays of the single
rectangular holes and slits with the areal coverage of only 12%. The terahertz transparency …

Understanding light interaction with metallic structures provides opportunities of
manipulation of light, and is at the core of various research areas including terahertz (THz) …

In this paper, a bandpass terahertz filter based on multilayer metamaterials is proposed,
designed and simulated numerically. To do this idea, first of all, the functional behavior …

Optical antenna is a nanoscale miniaturisation of radio or microwave antennas that is also
governed by the rule of plasmonics. We introduce various types of optical antenna and make …
