“…Orbital angular momentum (OAM) beam carries the orbital angular momentum with a helical phase, and the light field expression contains the phase factor jl e  associated with azimuth angle  and integer topological charges l. Because of its unique properties, the orbital angular momentum beam has a wide range of applications in micro-manipulation [36,37], communication [38,39], biomedicine [40] and information storage [41,42], and many other fields [43][44][45]. Here, we designed an encoding metasurface phase plate consisting of an array of 20*20 scatters that constructed by dividing the whole surface into eight consecutive segments.…”

In order to improve the transmitted efficiency of metasurfaces, the three-layer unit cell structure with coupling characteristics between layers was proposed. Using these Pancharatnam-Berry phase element particles with three-layer structure, we constructed encoded metasurfaces with different sequences to control the transmitted scattered waves. However, the manipulation of continuous transmission angle requires the continuous change of encoding metasurface period. Since the size of encoding particles in the coded metasurfaces cannot be designed to be infinitesimally small, it is impossible to obtain the continuously changing period of coded metasurfaces. In order to obtain the continuous manipulation of transmission scattering angles, we introduced the principle of Fourier convolution operation in digital signal processing on encoding metasurface sequences. By performing the addition and subtraction operation between two different encoding metasurface sequences, a new encoding metasurface sequence can be obtained with different scattering angle. The transmission scattering angles can be obtained continuously, and the terahertz wave can be manipulated freely. Moreover, by using the proposed threelayer highly efficient Pancharatnam-Berry phase encoding meta-atoms, these coded particles with different rotation angles can be precisely arranged to build the generators of the orbital angular momentum beam with different topological charges.

“…[31] Using these methods, high order transverse magnetic (TM) mode is applied to form the different OAM modes. [32] The design of the three-dimensional helical antenna is also a way to generate OAM beams. [33] Despite the generation of continuously-variable-mode OAM beams, this method relies on the special helical structure and the feed network, and therefore it is not easily integrated.…”

Orbital angular momentum (OAM) beam emitters with compact structure and high performance are highly desirable for wireless communication and radar technology. Here, we propose a compact emitter that only consists of a ring resonator and a feed line. Continuously-variable-mode OAM beams are generated by adjusting the wavelength and transmission path. The basic design principle and specific evaluation index are discussed. Both the simulated and experimental results demonstrate that the proposed emitter obtains the capacity of generating variable-modes. This approach opens a way for designing novel OAM beam emitter with desired properties.

“…One of the most important aspects of OAM-based communication system is how to generate vortex wave efficiently. There are several approaches to generating vortex wave, such as spiral phase plate [11], antenna arrays [13][14][15], holographic diffraction gratings [16], circular traveling-wave antenna [17,18], circular polarized patch [19], dielectric resonate antenna [20], multi-arm spiral patch [21], and metasurfaces [22][23][24][25][26][27][28][29]. Among them, metasurface is extraordinarily promising because of its unprecedented capability of modulating wavefronts of the electromagnetic wave.…”

In this paper, a monolayer metasurface that can simultaneously generate multi-mode vortex waves in ultra-wideband is proposed. Smooth phase variation is obtained by properly assigning the arm lengths of arrow-shaped metal on the top of the reflective metasurface unit cell. Different reflective cells are arranged in different sectors to form a phase-shifted surface that can convert a linearly polarized plane wave into a vortex wave. The full-wave simulations show that the designed reflective metasurface can generate vortex wave with multi-mode in ultra-wideband from 18 GHz to 42 GHz, which is in good agreement with the theoretical analysis. The proposed reflective metasurface paves an effective approach to generate vortex wave with multi-mode in ultra-wideband for OAM-based systems. Compared to the traditional ways of generating vortex waves, our design has the advantage of wide bandwidth.
