Orbital angular momentum (OAM) has recently attracted extensive attention in the radio
frequency domain due to its potential applications in various areas. In the OAM-based …

We describe the rich vortex dynamics at normal and near-normal or off-centered Laguerre-
Gaussian beam transmission through the q-plate–a waveplate capable of generating vortex …

EM waves with finite orbital angular momentum (OAM) have shown potential for a dramatic
increment in the RF channel capacities. Generation of OAM waves using microstrip …

Electromagnetic waves carrying orbital angular momentum (OAM and vortex waves) attract
much attention due to their specific characteristics and prospects for use in wireless …

Orbital angular momentum (OAM) modes can offer high density and high-capacity
communication. The traditional phased array antenna can only produce a limited number of …

Recently, flexible antennas have attracted great interest due to the variety of areas of their
practical use. Here we propose a design of a flexible antenna for generating …

In this paper, we present a novel RF OAM antenna design method using direct coaxial feed
with Circular Microstrip Antenna (CMA). By manipulating cylindrical harmonics through small …
