Abstract : It is shown that there exist physically realizable acoustic and electromagnetic sources for which the radiated field is exactly zero. Alternative analytical characterizations of these non-radiating sources are presented. Recently developed formulations of the inverse problem in acoustics and electromagnetics are introduced. The source is given as a solution of a Fredholm integral equation of the first kind. It is shown that the null space for this integral equation in each case is the class of non-radiating sources.
