Implementation of abrupt phase discontinuities along a surface has been the theme of
recent research on electromagnetic metasurfaces. Simple functionalities such as reflecting …

A survey of multi‐resonant antennas is comprehensively presented, with emphasis on
theoretical framework, design approaches, and practical examples. This article begins with a …

An omnidirectional circularly polarized (OCP) antenna operating at 28 GHz is reported and
has been found to be a promising candidate for device-to-device (D2D) communications in …

An ultralow-profile, electrically small, pattern-reconfigurable metamaterial-inspired Huygens
dipole antenna is presented that operates near 1.5 GHz. The design incorporates two pairs …

The efficacy of a simple, electrically small, low-profile, Huygens source antenna that radiates
in its broadside direction is demonstrated numerically and experimentally. First, two types of …

We propose a systematic approach for registering cross-source point clouds that come from
different kinds of sensors. This task is especially challenging due to the presence of …

It is demonstrated numerically that a metamaterial-inspired, low profile (height approximately
λ/80), electrically small (ka= 0.45) Huygens source antenna can be designed to radiate at …

Two 28 GHz, planar, electrically small Huygens source antennas are presented that are
broadside radiating and are based on multilayer PCB technology. The designs seamlessly …

A broadside radiating, linearly polarized, electrically small Huygens source antenna system
that has a large impedance bandwidth is reported. The bandwidth performance is facilitated …

Here we introduce the concept of'optimal particles' for strong interactions with
electromagnetic fields. We assume that a particle occupies a given electrically small volume …
