Scattering analysis of Bessel beam by a multilayered sphere

The scattering of an on-axis zero-order vector Bessel beam by a multilayered sphere is investigated within the generalized Lorenz–Mie theory. The detailed theoretical process of the scattering theory for the Bessel beam by a multilayered is presented, with special attention paid to the far-field scattering intensity. The present method is proved to be effective by the comparison of our results and the numerical results obtained from the surface integral equation method. Numerical results concerning the influences of different parameters of the incident Bessel beam and of the scattering body on the scattering intensity are displayed in detail. The study is expected to provide key support for understanding the interactions between Bessel beams and multilayered spheres.
