Numerical results of a straight chain cluster on-axis illuminated by A shaped beam

Based on the equations for multi-spheres scattering in plane wave, an shaped beam illuminating case interaction equations has been discussed. In the particular case where a straight chain cluster was located along the beam axis, some numerical results were presented. While discussions were made about these results. Finally, checking of the results in some special cases was done. While in general speaking, plane waves are special cases of shaped beams. All these discussions have many applications in many fields.
