Abstract

This paper According to the local approximate solution and finite series expression to the beam coefficients presented by Gouesbet and otherwise, we put forword a comprehensive recursive continued fraction algorithm and modify the defect of the existing algorithm, three key functions in scattering light intensity are recursively operated respectively, Mie scattering coefficient is obtained by using backward-recursive continued fraction algorithm, the highest recursive term is created automatically by computer and data fitting, the operation of angle function is carried out with Time forward-recurrence method, the beam coefficients equal to the local approximate solution and finite series expression, the relationship between scattering light intensity, gridling radius, particle size parameterer, relative refractive index and scattering angle is simulated based on MATLAB program and numerical calculation.
