Waveform Generation in the Near-Field Zone

We deal with an approach, based on the singular value optimization (SVO) technique, for the synthesis of array-based generators of near-field complex waveforms. The approach selects the grid wherein enforcing the design specifications and the radiator locations to control the ill-conditioning associated to the determination of the array excitations. Following the SVO optimization, the array coefficients are determined by a singular value decomposition. Numerical results are provided.
