In this paper, we review the generation of vortex beams carrying orbital angular momentum
in the microwave domain. We firstly present the theory of Laguerre–Gaussian beams where …

Artificially engineered metasurfaces provide extraordinary wave control at the
subwavelength scale. However, metasurfaces proposed so far suffer due to limited …

Metasurface provides a novel approach to control electromagnetic wave, and it attracts great
attention. But, it is still challenging to realize wavefront tailoring with dynamically switchable …

Traditional methods of generating vortex beams based on metasurfaces consist mainly in
modulating propagation phase or geometric phase. Here, by introducing detour phase, we …

The photonic spin Hall effect (PSHE) plays an important role in both fundamental science
and precision metrology. In this paper, we theoretically propose a polarization-dependent …

For many communication systems, including wireless networks, mobile, satellite, radar,
remote sensing, and many more applications, antenna arrays are very necessary. Utilizing …

In view of the fact that most invisibility devices focus on linear polarization cloaking and that
the characteristics of mid-infrared cloaking are rarely studied, we propose a cross-circularly …

Active metasurfaces incorporated with active elements can achieve tunable and/or
reconfigurable functionalities controlled by external stimuli, providing a new platform that …

Recently, there has been growing interest in the use of metamaterial (MTM)-based lenses,
also known as metalenses, as innovative antenna technology. Increasingly widespread …

Broadband tunable terahertz (THz) polarization converter is a vivid necessity due to its great
significance in functional utilization. Graphene is a promising material for the evolution of …
