We propose an azimuthally varying graded-index fiber that can efficiently create and control
a definite set of radial-index and orbital-angular-momentum (OAM) modes of Laguerre …

There recently has been increasing interest in the research and application of the rotational
Doppler effect (RDE), which paves a promising way to detect rotating objects remotely. In …

By using quantum electrodynamics in a dispersive medium, we describe scattering of plane-
wave and twisted photons by a slab made of a helical medium, the helix axis being normal …

Here, a novel family of stochastic electromagnetic sources called spatiotemporally partially
coherent partially polarized multi-Gaussian Schell-model vortex pulsed beams is proposed …

In this article, we present the design procedure of modulated metasurface leaky-wave
antennas (MMLWAs) to generate coaxial superposition of vortex beams with several orbital …

Orbital angular momentum (OAM) of electromagnetic waves is a field with a short history of
less than thirty years. Recent advances in modern technology have paved the way for the …

Uniform Circular Antenna (UCA) is a convenient way to generate multiple Orbital Angular
Momentum (OAM) beams simultaneously, and OAM-MIMO is promised to be an …

In this paper we combine the aperture field estimation technique and adiabatic Floquet-
wave expansion method for the analysis of leaky-wave holograms capable of generating …

The vortex wave mode provides wireless communications with a new orthogonal resource
for the multifold increase of spectrum efficiency. The rate splitting multiple access (RSMA) …

This article presents the generation of Orbital Angular Momentum (OAM) vortex waves with
mode 1 using Uniform Circular Array (UCA) antenna. Two different designs, namely, UCA-1 …
