Journal ArticleDOI
Single Gradientless Light Beam Drags Particles as Tractor Beams
TL;DR: This work investigates the optical forces by nonparaxial gradientless beams and finds that the forces can drag suitable particles all the way towards the light source.
Journal ArticleDOI
Elliptical dichroism: operating principle of planar chiral metamaterials
TL;DR: A homogenization technique based on the Lorentz electronic theory is employed to show that planar chiral structures (PCSs) can be described by an effective dielectric tensor similar to that of biaxial elliptically dichroic crystals.
Journal ArticleDOI
Negative propagation of vector Bessel beams
TL;DR: Energy characteristics of the superposition of TE- and TM-polarized electromagnetic Bessel beams are studied and the following phenomena are predicted, which should confirm negative beam propagation: reflection of the beam from a circular aperture and unusual movement of microparticles in the beam.
Journal ArticleDOI
Material-independent and size-independent tractor beams for dipole objects.
TL;DR: This Letter investigates and reports on the universality for a Bessel beam to be either a material-independent or size-independent optical tractor beam within the dipolar regime, and finds that the acoustic pulling force exhibits only size independence, owing to the acoustic scattering theory in contrast to the light scattering counterpart.
Journal ArticleDOI
Pulling cylindrical particles using a soft-nonparaxial tractor beam.
TL;DR: The cylindrical shape of dielectric particles can effectively mitigate the nonparaxiality requirements of a tractor beam, reducing the incidence angle of the partial plane waves of the light beam down to 45° and even to 30° for respectively dipole and dipole-quadrupole objects.
