WebMar 1, 2024 · Several theoretical and experimental approaches to create an optical pulling force have been undertaken. These methods include the use of optical conveyers [ 5,6], vortex beams [ 7,8], solenoid beams [ 9], enhancing the forward scattering of photons [ 10] and utilising the photophoretic force [ 11]. WebAnother typical example is the so-called optical solenoid beams, which come from the solutions of the Helmholtz equation as a particular superposition of m-th order Bessel beams, propagating without diffraction with their principal intensity maximum spiraling around the optical axis [ 29 ]. north korean defector ted talk
