Abstract :
In this paper, the far-field of a spherical array of point dipoles is related to the array currents in an elegant manner by invoking the properties of the associated Legendre functions. The inverse problem, viz., determining the array currents from the far-field data is solved in a recursive manner thereby precluding the need for a matrix inversion
