“…It is shown that laser beams with Gaussian-like intensity profile should be used to trap particles with refractive index bigger than that of the ambient, while laser beams with a hollow-like intensity profile are applicable to trap particles with refractive index smaller than the ambient. In addition, it is noted that some other beams such as Hermite-Gaussian beam [21,22], on-axis circularly symmetric Bessel beam [23], Laguerre-Gaussian beam [24], radially polarized beam [25,26], vortex beam [27][28][29], and circular Airy beams [30] also have been explored. These beams have great application prospects in free space information transmission and optical communication [31][32][33], optical imaging [34] and optical manipulation [35][36][37].…”

The intensity distributions near the focus for radially polarized Bessel–Gaussian beam with conical phase by a high numerical aperture objective are computed based on the vector diffraction theory. Results show that the circular focal spot can be changed from one to two on the focal plane by adjusting the truncation parameter β. By increasing the phase modulation parameter L, the focal pattern appeared focal shift. According to the intensity distribution, the forces acting on a particle are calculated. The stability of particle trapping is analyzed. It is shown that a tightly focused radially polarized Bessel–Gaussian beam with conical phase is applicable to trapping, separating and transporting of particles.

Previous JQSRT special issues devoted to the "Laser-light and Interactions with Particles (LIP)" conferences were accompanied by prefaces written for issues published in a single volume, followed by peer-reviewer papers based on the topics discussed, but not necessarily presented, during the conferences, see [1] in [2], [3] in [4], and [5] in [6]. Papers associated to the LIP-conference in 2018 however, have been published as a virtual topical issue, the word "virtual" meaning that the papers have been published once they have been accepted, rather than collected in a single issue of JQSRT. In other words, the authors of accepted manuscripts have seen their papers o¢ cially published without having to wait for the rest of the manuscripts to get accepted. The corresponding preface/afterword was published in 2019 [7]. The 2020 conference was scheduled to be held in Warsaw, Poland, but has been postponed to 2022 due to the Covid pandemic. It has been decided, nevertheless, to publish another virtual issue of JQSRT to limit the e¤ects of the impact of the pandemic and stick to a tradition as much as possible.LIP conferences were in the …liation of a series of conferences which started under the name of "Optical Particle Sizing, OPS, theory and practice" in Rouen,
