The use of the millimeter wave (mmWave) spectrum and further exploration of sub-mmWave
has led to a new era in wireless communication, as the need for higher data rates grows …

We demonstrate switchable unidirectional propagation of slow waves of coupling within a
metamaterial array of strongly coupled elements. We predict theoretically and verify …

In this communication, two compact and high-gain magnetic dipole antennas (MDAs) with
and without a metallic ground are developed by utilizing an endfire superdirective array …

A directive planar endfire antenna with high gain and miniaturized size is proposed. By
utilizing the higher-order mode currents of the dipole, the antenna achieves the endfire …

We propose a simple and rapid way of optimising directivity in metamaterial-inspired endfire
antenna arrays with strong inter-element coupling. We introduce, in addition to the traditional …

The superposition of resonances in a subwavelength particle can be used to achieve
powerful scattering beyond the single channel limit and can also determine the directionality …

In this paper, we present a general theory of aperiodic subwavelength arrays for controlling
electromagnetic waves. The considered platform is formed by an array of electrically small …

Superdirective antennas developed over the last century have received renewed interest in
recent years from the development of metamaterials. These arrays of electromagnetic …

Here, the authors propose a new approach for realising wideband and polarisation‐
independent antireflection coating, based on a metamaterial composed of a subwavelength …

This chapter presents the application of planar microwave sensors based on coupled
resonators for the detection of solute concentration in aqueous solutions. First, the dielectric …
