“…Despite the considerable research on optical invariant beams, a general description of the Poynting vector in nonparaxial beams has not been presented, and the applications previously mentioned still remain unexplored for the Weber beam case. A need to understand their physical properties is necessary due to recent interesting works that have been reported using invariant beams, such as optical surfaces waves [34,35], application in laser beam shaping [36], meta-surfaces [37], optical forces [38], scattering [39], among others. Many of these works, however, are based on plane waves and attempts with Bessel beams.…”

Negative propagation is an uncommon response produced by the local sign change in Poynting vector components. We present a general Poynting vector expression for all invariant beams with cylindrical symmetry using scalar potentials in order to evaluate the possibility of negative propagation. We analyze the plausibility of negative propagation being independent of mode mixing; we study Weber beams as a particular case. The study of this negative effect allow us to advance in the field of micro manipulation and understanding of optical forces. Applications of these beams are discussed.

“…Although the ideal Bessel beams with infinite transverse extent and energy cannot be produced experimentally, the quasi-Bessel beams with finite size approximation can be generated by use of holographic elements [2], an axicon [3,4,5], a Spatial Light Modulator (SLM) [6], a conical mirror [7] or a Digital Micro Mirror device (DMD) [8]. Because of their special properties, such as non-diffraction [1], selfreconstruction [9] and superluminality [10], Bessel beams have prospective applications in the fields of optical manipulation [11], the design of optics devices, imaging [12] and communication [13]. Most noteworthy, investigation results show that beams with orbital angular momentum (OAM), which are also called vortex beams, have great potential in improving the communication efficiency [14][15][16], hence the high-order Bessel beams [17][18][19], which belong to a class of OAM beams, are worthy of more attention.…”

This paper investigates the characteristics of reflected and transmitted fields of a vector Bessel vortex beam through multilayered isotropic media on the basis of the vector angular spectrum expansion and presents the effects of media on intensity, phase, and polarization. The method is verified by studying the reflection and transmission on a single interface at vertical incidence. For both paraxial and nonparaxial incident beam cases, numerical simulations of the field components and the time-averaged Poynting vector power density of the reflected and transmitted beams for the three-layered media are presented and discussed in detail. It is shown that as the incident angle increases, the magnitude distribution of the reflected beams illustrates significant distortions and no longer represents similar patterns to that of the incident beam, whereas the magnitude distribution of the transmitted beams can maintain similar profiles to the incident beam, apart from the notable distortion of the central ring. For the same incident angle, the effects of media on the magnitude distribution for the nonparaxial case are more evident than those for the paraxial case. The results of phase distribution and polarization of the reflected and transmitted fields show that as the incident angle increases, the distortion of the phase distribution and polarization for the reflected fields are more significant and the topological charge cannot be preserved.

“…Moreover, the HOBVB resists diffraction over an extended distance of several wavelengths, and has the capability to reform [35][36][37][38] after encountering an obstruction, as long as the whole beam is not blocked. In addition, a HOBVB has the capability of inducing a negative pulling radiation force [39][40][41][42][43][44] as well as spin [45,46] and orbital [46] torque reversal [45][46][47][48] depending on the beam parameters.…”

“…All these properties make the optical HOBVB an attractive candidate from the standpoint of particle manipulation and handling applications. Various investigations recognizing the importance and utility of the HOBVB considered the case of a sphere, and examined the resonance scattering [49], radiation forces [42,43,50,51] and torques [45,46,48]. Nonetheless, in some instances, the actual shapes of a variety of objects deviate significantly from the spherical geometry.…”

The optical radiation force, spin and orbital torques exerted on a subwavelength prolate gold spheroid coated by a layer of plasmonic material with negative permittivity and illuminated by either a zerothorder (non-vortex) or a first-order vector Bessel (vortex) beam are computed in the framework of the electric dipole approximation method. Calculations for the Cartesian components of the optical radiation force on a subwavelength spheroid with arbitrary orientation in space are performed, with emphasis on the order (or topological charge), half-cone angle of the beam, and the plasmonic layer thickness on-and off-resonance. A repulsive (pushing) force is predicted for the layered subwavelength prolate spheroid, on-and off-resonance along the direction of wave propagation. Moreover, the Cartesian components of the spin radiation torque are computed where a negative longitudinal spin torque component can arise, suggesting a rotational twist of the spheroid around its center of mass in either the counter-clockwise or the clockwise (negative) direction of spinning. In addition, the longitudinal component of the orbital radiation torque exhibits sign reversal, indicating a revolution around the beam axis in either the counter-clockwise or the clockwise directions. The results show that the plasmonic resonance strongly alters the force, spin and orbital torque components, causing major amplitude enhancements, signs twists, and complex distributions in the transverse plane.
