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 …

Leaky waves have been among the most active areas of research in microwave engineering
over the second half of the 20th century. They have been shown to dominate the near-field …

We propose a design of a dielectric (silicon nitride) optical leaky wave antenna (OLWA) with
periodic semiconductor (silicon) corrugations, capable of producing narrow beam radiation …

An efficient and compact coupler—a device that matches a microwaveguide and a
nanowaveguide—is an essential component for practical applications of nanophotonic …

We investigate experimentally the parameter space defining, in the visible range, the far-
field diffraction properties of a single circular subwavelength aperture surrounded by …

We experimentally demonstrate terahertz Bessel beamforming based on the concept of
plasmonics. The proposed planar structure is made of concentric metallic grooves with a …

We present a detailed analysis of the optical properties of one-dimensional arrays of slits in
metal films. Although enhanced transmission windows are dominated by Fabry-Perot cavity …

Nanoscale wells have been fabricated in a chip to construct a photonic crystal that is used
for enhanced immunoassays of a common food-borne toxin, Staphylococcal enterotoxin B …

A 2-D periodic leaky-wave antenna is studied to examine the mechanism of beam formation
from leaky-wave modes and the properties of the leaky-wave modes. The structure consists …

A study of the radiation characteristics of a 2-D periodic leaky-wave antenna (LWA)[ie, one
that radiates from higher order space harmonics (Floquet waves) instead of the fundamental …
