Complex Rays Expansion of Three Dimension Radiation Pattern Using Buckyball Grid

The method of complex rays expansion of three dimensions radiation pattern is proposed basing on the Gauss characteristic of the paraxial far fields from complex source. The Gauss beams shooting from the origin to the gird nodes of the Buckyball distribute uniformly in all directions. The effect of the parameters of beam width and discrete interval to the simulation of pattern are analyzed, and the experiential choices of the parameters are given. The simulative results show a high simulative precision.
