The physics and applications of a broad class of artificial electromagnetic materials
composed of lattices of aligned metal rods embedded in a dielectric matrix are reviewed …

Metamaterials (MTMs) are artificially engineered materials with unique electromagnetic
properties not occurring in natural materials. MTMs have gained considerable attention …

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 …

In this communication, a coplanar waveguide-fed, compact, wideband dual-ring slot antenna
for biomedical applications in the Industrial, Scientific and Medical frequency band is …

This communication presents a metamaterial (MTM)-loaded compact dual-band circularly
polarized antenna system suitable for multiple bio-telemetric applications. The proposed …

A horn antenna includes a conducting horn having an inner wall and a first dielectric layer
lining the inner wall of the conducting horn. The first dielectric layer includes a metamaterial …

In this letter, a novel high-directivity microstrip patch antenna (MPA) based on planar zero-
index metamaterials is presented. An averaging effect over the metamaterial structure yields …

A compact wideband metamaterial absorber (MA) for Ku band applications is presented in
this paper. Ku band is a part of a microwave frequency spectrum ranging from 12 to 18 GHz …

Guided-wave structures are the foundation for the design and development of RF and
microwave circuits and systems. Whether it is planar or nonplanar, periodic or straight, a …

The design of a miniaturized CPW-fed ring slot antenna using interdigitated slits is
presented. The fundamental resonant frequency of the ring slot antenna was reduced …
