This book deals with theoretical bases of the modern optics division concerned with
coherent light fields with singularities characterized by phase uncertainty. Singular light …

The formation of high-order Bessel beams by a passive acoustic device consisting of an
Archimedes' spiral diffraction grating is theoretically, numerically, and experimentally …

The Airy acoustical beam exhibits parabolic propagation and spatial acceleration, meaning
that the propagation bending angle continuously increases before the beam trajectory …

This paper reports the fabrication, characterization, and microparticle manipulation
capability of an adjustable multi‐scale single beam acoustic tweezers (SBAT) that is capable …

This book gives insight into the theoretical backgrounds of optical vortices and their
propagation in free space and simple optical systems. The author's theoretical analysis …

Unlike standard dielectric materials, the interaction of light-sheets of arbitrary wavefronts
with a particle exhibiting circular dichroism, such as chiral, topological insulator, liquid …

The theoretical formalism for acoustical Bessel vortex (helicoidal) tractor beams and results
presented here are the first to demonstrate the emergence of a pulling force of attraction on …

The extended optical theorem is generalized for scalar acoustical beams of arbitrary
character with any angle of incidence interacting with an object of arbitrary geometric shape …

We considered nonparaxial asymmetrical Bessel modes of the first and second types, which
differ from a conventional symmetrical Bessel mode by a real-valued shift along one …

Based on the partial-wave series expansion (PWSE) method in spherical coordinates, a
formal analytical solution for the acoustic scattering of a zeroth-order Bessel acoustic beam …
