In order to satisfy the power thirst of communication devices in the imminent fifth generation
era, wireless charging techniques have attracted much attention both from the academic and …

We present here a method for generating second-harmonic beams with tailored beam
profiles using nonlinear metasurfaces based on split ring resonators. By manipulating both …

Conventional vortex beams carrying orbital angular momentum (OAM) suffer from the
limitation of beam divergence in wireless communications applications. This article …

In this letter, a millimeter-wave (mm-wave) nondiffracting Airy orbital angular momentum
(OAM) beam is experimentally demonstrated by using a single-layer hexagonal lattice …

The Airy beam, known to present particular unique features, such as diffraction-free, self-
healing, and self-bending, has attracted considerable interest in recent years. Here, an …

In this article, a 2-D Airy beam is experimentally generated at microwave frequency by using
a simple and thin metasurface composed of a single-layer of square C-shaped …

A key challenge in millimeter-wave and terahertz wireless networks is blockage of the line-of-
sight path between a base station and a user. User and environmental mobility can lead to …

Airy beam is a diffraction-free mode which exhibits the exotic properties of self-accelerating
propagation and self-healing, and for this reason, it has been largely investigated in the …

We propose a method for directly constructing three-dimensional (3-D) accelerating beams
with twisted wavefront amplitude and phase profiles in real space. The design strategy …

We show that it is possible to independently control both the trajectory and the maximum
amplitude along the trajectory of a paraxial accelerating beam. This is accomplished by …
