Fifth generation (5G) mobile communication systems have entered the stage of commercial
deployment, providing users with new services, improved user experiences as well as a host …

Vortex electromagnetic wave carries the Orbital Angular Momentum (OAM), and thus has a
spiral wavefront structure, which contains the azimuthal information of the target in the echo …

We have proposed a fast super-resolution (FSR) imaging based on the electromagnetic
(EM) OAM (orbital angular momentum) radar. The proposed method only needs to transmit …

In this paper, a double-layer acoustic metasurface (DAM) composed of a fixed lower
acoustic metasurface (LAM) and a rotatable upper acoustic metasurface (UAM) is proposed …

Spatial division multiplexing using conventional orbital angular momentum (OAM) has
become a well-known physical layer transmission method over the past decade. The mode …

For the application of vortex electromagnetic (EM) beams in practical detection scenes, the
scattering characteristics of electrically large arbitrarily shaped targets illuminated by an off …

Micro-Doppler shift induced by precession is crucial for ballistic target recognition. However,
traditional single radar has the limitation of single viewing angle, while radar network (RNW) …

A new class of iterated linearization-based nonlinear filters, dubbed dynamically iterated
filters, is presented. Contrary to regular iterated filters such as the iterated extended Kalman …

The obstacle in a channel is a typical scenario for free-space optical (FSO) communications,
however, it will destroy the information in channels, especially for the orbital angular …

Despite the significant interest in pattern synthesis over the decades, the beam synthesis of
orbital angular momentum (OAM) has received relatively little attention. In this article, we …
