    This paper presents a technique for the control of the sideband radiations in time-modulated planar arrays. The proposed method is aimed at generating a desired pattern at the carrier frequency as well as reducing the power losses and the interferences related to the harmonic radiations. By acting on both the durations and the commutation instants of the time pulses controlling the element switches, the method based on a Particle Swarm Optimizer is applied. Representative results are reported and discussed to show the effectiveness of the proposed approach.
