Electromagnetic absorbers have drawn increasing attention in many areas. A series of
plasmonic and metamaterial structures can work as efficient narrowband absorbers due to …

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 large amount of light emitted from a light emitting diode (LED) being trapped inside the
semiconductor structure is the consequence of the large value of the refractive index. The …

Extraordinary transmission and other interesting related phenomena for 1-D periodic arrays
of slits (compound diffraction gratings) have recently been the object of intense research in …

We present 2D measurements of the full THz electric field behind a sample consisting of
multiple slits in a metal foil. Our measurements, which have a sub-wavelength spatial, and a …

In the study of electromagnetic wave propagation and scattering, researchers have always
faced the dichotomy of dealing directly with Maxwell's equations (and their complicated …

Very recently, in a short letter [Appl. Phys. Lett. 91, 111111 (2007)], we outlined some
important results of electromagnetic transmission in dual-metallic grating structures …

We introduce the subwavelength transmission of an effective surface plasmon beyond the
light zone via the proximity interaction of convection electrons with a metal grating. A …

In optical frequency, surface plasmons of metal provide us a prominent way to build compact
photonic devices or circuits with non-diffraction limit. It is attributed by their extraordinary …

Metallic compound gratings are studied in this work by means of an analytical equivalent
circuit approach in order to obtain its transmission and reflection properties when illuminated …
