Abstract :
The concept of radiation from a distribution of oscillating current at a complex location can be used to describe the aberrations of a Gaussian beam. First-order theory requires an electric dipole for representing a beam. Third-order theory calls for a pair of electric dipoles, magnetic dipoles, and electric quadrupoles.
