Completely Chiral Optical Force for Enantioseparation. [PDF]
Sci Rep, 2016 AbstractFast and reliable separation of enantiomers of chiral nanoparticles requires elimination of all the forces that are independent of the nanoparticle handedness and creation of a sufficiently strong force that either pushes different enantiomers in opposite directions or delays the diffusion of one of them with respect to the other.

Multi force optical tweezers to generate gradients of forces
Optics Express, 2004 We present a multi trap optical tweezes system that enables to generate two-dimensional dynamical configurations of focal spot where the trapping force of each element of the pattern can be individually changed. Force gradients in the pN range can be generated on a micrometer scale.

Optical Bernoulli forces [PDF]
Physical Review A, 2013 By Bernoulli's law, an increase in the relative speed of a fluid around a body is accompanies by a decrease in the pressure. Therefore, a rotating body in a fluid stream experiences a force perpendicular to the motion of the fluid because of the unequal relative speed of the fluid across its surface.

Tailoring Optical Gradient Force and Optical Scattering and Absorption Force [PDF]
Scientific Reports, 2017 AbstractThe introduction of the concept of gradient force and scattering and absorption force is an important milestone in optical trapping. However the profiles of these forces are usually unknown, even for standard setups. Here, we successfully calculated them analytically via multipole expansion and numerically via Mie theory and fast Fourier ...

Optical forces in nanorod metamaterial [PDF]
Scientific Reports, 2015 AbstractOptomechanical manipulation of micro and nano-scale objects with laser beams finds use in a large span of multidisciplinary applications. Auxiliary nanostructuring could substantially improve performances of classical optical tweezers by means of spatial localization of objects and intensity required for trapping.

Mitigation of GNSS Time Synchronization Attacks in a Multicorrelator Receiver
IEEE Access, 2022 Global navigation satellite systems (GNSSs) are widely used in various fields to provide high-precision timing. However, their low signal power and open signal structure render GNSS receivers vulnerable to time synchronization attacks (TSAs).
