Orbital angular momentum (OAM) has aroused a widespread interest in many fields, especially in telecommunications due to its potential for unleashing new capacity in the severely congested spectrum of commercial communication systems. Beams carrying OAM have a helical phase front and a field strength with a singularity along the axial center, which can be used for information transmission, imaging and particle manipulation. The number of orthogonal OAM modes in a single beam is theoretically infinite and each mode is an element of a complete orthogonal basis that can be employed for multiplexing different signals, thus greatly improving the spectrum efficiency. In this paper, we comprehensively summarize and compare the methods for generation and detection of optical OAM, radio OAM and acoustic OAM. Then, we represent the applications and technical challenges of OAM in communications, including free-space optical communications, optical fiber communications, radio communications and acoustic communications. To complete our survey, we also discuss the state of art of particle manipulation and target imaging with OAM beams.

“…Also, a finite size source can only generate pseudo-Bessel beam which possesses the nature as an ideal Bessel beam within a limited distance [14][15][16][17][18][19], so the methods and devices to generate high-performance Bessel beam are extremely challenging. There are some feasible methods proposed to generate high-order Bessel vortex beams in microwave bands, such as transmitarray [20][21][22] and reflective metasurface with polarizer [23]. However, when the electromagnetic energy passes through the dielectric, there will be some energy loss, which is not conducive to the conversion efficiency of energy.…”

In this paper, we propose a method to generate a high-order Bessel orbital angular momentum (OAM) vortex beam by using a single-layer reflective metasurface, which integrates the advantages of small size, high efficiency, insensitive polarization and stable incident angles. An offset-fed horn configuration is adopted to overcome the feed-blockage effect, and a subwavelength unit cell with rotational symmetry is designed to cover the reflection phase variation range of 360° in different incident angles. The metasurface is simulated, fabricated and measured at the center frequency of 10 GHz, and the results validate that a second-order Bessel OAM vortex beam can be generated effectively. By comparing the field distributions between the Bessel OAM vortex beam and the conventional OAM vortex beam, we find that the generated Bessel OAM vortex beam is obviously more convergent and has more stable field distributions. The single-layer reflective metasurface is simple and flexible to shape the wavefront to be a Bessel OAM vortex wave, which has the potential to be used in a wide range of applications.

“…The traditional OAM wave has diffraction scattering. Bessel beam has nondiffraction propagation characteristic, so it is a possible method to solve the problem of energy concentration of OAM wave by making Bessel wave carry OAM . The zero‐order Bessel wave itself does not carry OAM.…”

“…The transmission metasurface can adjust the phase distribution of the electromagnetic wave, which has the advantages of flexible design, low profile, light weight and easy manufacture, and so forth. Some Bessel beam generators carrying OAM have been successfully designed using transmission metasurfaces . In this work, we have designed an antenna that generates Bessel carrying OAM and traditional OAM wave at 31~36 GHz using a wideband transmission metasurface.…”

Orbital angular momentum (OAM) microwave waves have received increasing research interest because of their potential to improve communication capacity and radar resolution. However, the traditional orbital angular momentum wave has the problem of diffraction divergence. The ideal Bessel beam with orbital angular momentum has the property of nondiffraction. Hence, the Bessel beam carrying orbital angular momentum has great research potential. In this work, a wideband transmission metasurface for generating Bessel beam carrying OAM is designed, fabricated, and measured. And it is the first experimental to show that the Bessel beam carrying OAM has higher gain and lower crosstalk than the traditional OAM wave in far field transmission.
