Future wireless systems integrating communication and sensing will require handling an
enormous amount of data with extremely low latency. Intense video streaming data traffic …

Poincaré beams have a spatial mode that correlates transverse spatial coordinates with
states of polarization. The state of polarization may vary along one coordinate. For example …

We study the propagation of off-axis vortices in a paraxial beam formed by two collinear
Laguerre-Gauss beams. We show that the vortices move about the beam axis as the light …

The generation, propagation, and detection of high-quality and coherently superimposed
optical vortices, carrying two or more orbital angular momentum (OAM) states, is …

In this Letter, we propose an orbital angular momentum (OAM) sensor to simultaneously
measure the dynamic micro-displacement and the direction of a moving object in real time …

This book is devoted to the consideration of unusual laser beams–vortex or singular beams.
It contains many numerical examples, which clearly show how the phase of optical vortices …

Patch antennas are among the most popular radiating elements, yet their quasi-2-D
structure reduces the degrees of freedom available to tailor their radiation pattern. To …

To achieve a smart electromagnetic (EM) environment, several implementation challenges
need to be addressed. Among them, the practical realization of low-cost and easily …

We generate experimentally optical ring lattice structures which are the superposition of two
coaxial Laguerre–Gaussian modes with common waist position and waist parameter …

Recent years have witnessed an increasing interest in topological states of condensed
matter systems, whose concepts have been also extended to wave phenomena. Especially …
