Metamaterials are being applied to the development and construction of many new devices
throughout the electromagnetic spectrum. Limitations posed by the metamaterial operational …

We describe a new electrochemical method for reversible, pump-free control of liquid
eutectic gallium and indium (EGaIn) in a capillary. Electrochemical deposition (or removal) …

The issue of asset tracking in dense environments where the performance of the global
positioning system (GPS) becomes unavailable or unreliable is addressed. The proposed …

In this paper, we propose a novel electrically small dual-band reconfigurable antenna. By
using a compact eighth-mode substrate integrated waveguide (EMSIW) structure, we …

Frequency-reconfigurable antennas seem a viable solution to achieve better performance
and increased flexibility for integrated mobile phone antennas. Due to the lossy nature of …

A simple, frequency-agile, efficient, near-field resonant parasitic (NFRP) monopole antenna
is presented. The NFRP element is a capacitively-loaded loop (CLL) augmented with a …

Conjugated polymers (CPs) undergo a wide range of reversible intrinsic property changes
including electrical conductivity, electromagnetic absorption, volume, and charge mobility …

In recently developed wireless communication systems, circular polarization (CP) antennas
are used for communication links to reduce the natural loss effect in receivers. Therefore, in …

A frequency-agile, efficient, circularly polarized (CP), near-field resonant parasitic (NFRP)
antenna is presented. It consists of two orthogonal capacitively loaded loops (CLLs) with …

A multilayered metamaterial-inspired antenna with a pixel grid loading structure is
introduced. The antenna consists of two patterned metal layers separated by a thin dielectric …
