Planar microwave sensors have become increasing developed in recent decades,
especially in material characterization (solid/liquid) as they provide regions highly sensitive …

A new type of nature-inspired global optimization methodology based on atmospheric
motion is introduced. The proposed Wind Driven Optimization (WDO) technique is a …

A dual-band and polarization-independent electromagnetic energy harvester composed of
an array of pixelated unit cells is proposed. The pixelated unit cell is basically a dual-band …

Frequency-selective surfaces (FSSs) have many applications in spatial filtering of
electromagnetic waves and are commonly used in antennas, polarizers, radomes, and …

A highly sensitive microwave near-field sensor based on electrically-small planar resonators
is proposed for highly accurate characterization of dielectric materials. The proposed sensor …

A fully automated approach for designing metasurfaces whose unit cell may include metallic
vias is proposed. Towards this aim, a ternary version of the particle swarm optimization …

Several approaches in the literature have been attempted for reducing the radar cross-
section (RCS) of antennas, specifically for planar patch antennas. Ideally, the antenna …

A wideband, thin, and multilayer (planar) microwave absorber is designed in this paper. The
absorber is a periodic array of cells which includes three patterns of resistive film on two …

This letter introduces a systematic procedure to reduce the mutual coupling (MC) between
radiating elements in a microstrip array antenna. The proposed method is based on using …

Electromagnetic metasurfaces are planar two-dimensional metamaterials, typically of
subwavelength thickness. Unit cell elements of different shapes have been widely explored …
