This review paper summarizes various aspects of directive beaming and explains these
aspects in terms of leaky waves. Directive beaming occurs in antenna design where a …

By using the rigid full-vectorial three-dimensional finite-difference time-domain method, we
show that the enhanced transmission through a metallic film with a periodic array of …

Extraordinary optical transmission of light or electromagnetic waves through metal plates
periodically perforated with subwavelength holes has been exhaustively analyzed in the last …

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 …

The goal of this paper is to overview radio-frequency (RF) electromagnetic interactions with
solid and liquid materials from the macroscale to the nanoscale. The overview is geared …

Metamaterial structures are artificial materials that show unconventional electromagnetic
properties such as photonic band-gap, extraordinary optical transmission and left-handed …

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 …

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 …

Many frequency-selective surface (FSS) structures are based on the use of a single periodic
array of slot/apertures in a conducting sheet embedded in a layered medium. However, it is …

A novel periodic structure, made of an arbitrary number of stacked subwavelength hole
arrays, exhibiting simultaneously electromagnetic band gap, extraordinary transmission and …
