Generation of high-order Bessel vortex beam carrying orbital angular momentum using multilayer amplitude-phase-modulated surfaces in radiofrequency domain

Abstract: A high-order Bessel vortex beam carrying orbital angular momentum (OAM) is generated by using multilayer amplitude-phase-modulated surfaces (APMSs) at 10 GHz. The APMS transmitarray is composed of four-layer conformal square-loop (FCSL) surfaces with both amplitude and phase modulation. The APMS can transform a quasi-spherical wave emitted from the feeding source into a pseudo non-diffractive high-order Bessel vortex beam with OAM. The APMS for a second-order Bessel beam carrying OAM in the n = 2 mode is desig… Show more

“…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.…”

“…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.…”
