Metamaterials are artificially engineered novel substances (or matter) that exhibit properties
not found in nature. One of the earliest examples of a metamaterial structure is the split-ring …

This paper gives a basic review and a summary of recent developments for leaky-wave
antennas (LWAs). An LWA uses a guiding structure that supports wave propagation along …

Metamaterials are materials typically engineered with novel or artificial structures to produce
electromagnetic properties that are unusual or difficult to obtain in nature. Because of their …

An investigation into the design of compact patch antennas loaded with complementary split-
ring resonators (CSRRs) and reactive impedance surface (RIS) is presented in this study …

In this paper, we propose an approach to realize substrate integrated waveguide (SIW)-
based leaky-wave antennas (LWAs) supporting continuous beam scanning from backward …

Composite right/left-handed (CRLH) substrate integrated waveguide (SIW) and half mode
substrate integrated waveguide (HMSIW) leaky-wave structures for antenna applications are …

The plasmonic waveguide made of uniform corrugated metallic strip can support and guide
spoof surface plasmon polaritons (SSPPs) with high confinements. Here, we propose …

A novel technique for the elimination of the open stopband in one-dimensional periodic
printed leaky-wave antennas is presented. A quarter-wave transformer, or alternatively a …

Metamaterials are understood to be artificially engineered materials that exhibit unusual or
difficult to obtain electromagnetic (EM) properties. Such properties would include negative or …

A glide-symmetry Goubau line leaky-wave antenna for achieving both high scanning rate
and wide scanning angle range is introduced. The novelty of the design is its combination of …
