Abstract

     In this paper, we use the integral localized approximation for computing the beam shape coefficients (BSCs) for Mathieu beams. These coefficients are of great interest in the description of beams in the generalized Lorenz-Mie theory. The BSCs are used in the calculation of the scattered field components by homogeneous sphere. For sake of the simplicity, we use the BSCs in calculating the far-field components of scattered Mathieu beams. All through this work, the effects of various parameters on the scattered intensity are analysed numerically.
