Zhou, X. Chu] By means of the method of vector angular spectrum representation and the mathematical techniques, the analytically vectorial structure of the circular flattened Gaussian beam (CFGB) is derived without any approximation, which can be applicable to an arbitrary observation plane. In the far-field, the analytical formulae of the TE and the TM terms are further simplified using the method of stationary phase. The analytical expressions of the energy flux for the TE term, the TM term, and the CFGB are also presented. The energy flux distributions of the TE term, the TM term, and the CFGB are demonstrated in different reference planes, and the evolvement of the patterns of the TE term, the TM term, and the CFGB upon propagation are graphically illustrated.
