Optical gradient force on chiral particles
WebApr 3, 2024 · [31, 33, 34] Flexible microswimmers based on the self-assembly of magnetic nanoparticles are possible to generate propulsion by force deformation into a chiral structure under a rotating magnetic field (RMF), which are independent with the solid surface and exhibit a controlled motion in viscous fluid. These non-invasive and easily replicated ... WebWe introduce a novel phase-only diffractive optical element called chiral binary square axicon (CBSA). The CBSA is designed by linearly rotating the square half-period zones of the binary square axicon with respect to one another. A quadratic phase mask (QPM) is combined with the CBSA using modulo-2π phase addition technique to bring the far-field …
