The letter describes an efficient computational technique, based on a sampling approach, for the evaluation of the far-field radiation integral of an arbitrary source distribution. The technique virtually eliminates any redundancy of computation by reducing to a minimum the number of elements of information required for a satisfactory radiated field reconstruction. These elements, in turn, can be efficiently computed by a proper fast Fourier transform algorithm.

Abstract
The letter describes an efficient computational technique, based on a sampling approach, for the evaluation of the far-field radiation integral of an arbitrary source distribution. The technique virtually eliminates any redundancy of computation by reducing to a minimum the number of elements of information required for a satisfactory radiated field reconstruction. These elements, in turn, can be efficiently computed by a proper fast Fourier transform algorithm.File in questo prodotto:
