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 …

BACKGROUND Maximum directivity from a horn antenna may be obtained by uniform
amplitude and phase distribution over the horn aperture. Such horns are denoted as …

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 …

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 …

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 …

In this study, a metamaterial (MTM)‐based high‐gain compact‐wearable antenna for 2.45
GHz industrial, scientific and medical radio band application has been proposed. To achieve …
