Abstract
Based on Generalized Lorenz-Mie Theory (GLMT), the scattering phenomenon caused by Bessel beam irradiation on metal particles is studied. The order and polarization mode of Bessel beam, as well as the influence of the size of metal particles on the total intensity distribution of the light field around metal particles are investigated by using the software simulation calculation. The results show that for spherical metal particles of the same size, the higher order Bessel beam is more likely to bypass the metal particles in the forward propagation, while the lower order Bessel beam bypassed the particles in the propagation is related to the beam polarization mode. The results have potential applications in microscopy super-resolution imaging and detection of tiny particles.
