Abstract：The scattering of an electromagnetic high-order Bessel trigonometric beam by several typical homogeneous dielectric particles is investigated. The incident beam is represented by the vector expressions in Cartesian coordinates. The scattering problems involving homogeneous dielectric particles are formulated with the surface integral equation method. As an example, the effects of the beam's parameters on the differential scattering cross section for a sphere are analyzed in detail. Then the numerical results for the scattering of a high-order Bessel trigonometric beam by three typical nonspherical particles, including a spheroid, a cylinder, and a cube, are presented.
