Abstract
A formulation based on Lagrangian optimization and spheroidal vector
wave functions is presented for the vector electromagnetic inverse
source problem of deducing a time-harmonic current distribution that is
confined within a spheroidal volume, that generates a prescribed
radiation field, and that is subject to given constraints on the source
functional energy, which characterizes antenna current level, and the
source's reactive power, which models antenna resonance matching. The
paper includes computer simulation results illustrating the derived
inverse theory.
