In wireless power transfer (WPT) applications the weakest contribution to the overall link efficiency is the effective selection of the zone to be powered. Hence, the need for smart transmitting architectures is strong. In this contribution, two promising families of highly-reconfigurable arrays are presented: first, time-modulated arrays are considered as a powerful tool for selective WPT, through the exploitation of the sideband radiation phenomenon; frequency-diverse arrays are, then, proposed for a smarter radiation, able to focus the beam in range, too. In both these cases, the accurate nonlinear/electromagnetic analysis approach, relying on the Harmonic Balance technique, demonstrates its effectiveness.

Abstract

In wireless power transfer (WPT) applications the weakest contribution to the overall link efficiency is the effective selection of the zone to be powered. Hence, the need for smart transmitting architectures is strong. In this contribution, two promising families of highly-reconfigurable arrays are presented: first, time-modulated arrays are considered as a powerful tool for selective WPT, through the exploitation of the sideband radiation phenomenon; frequency-diverse arrays are, then, proposed for a smarter radiation, able to focus the beam in range, too. In both these cases, the accurate nonlinear/electromagnetic analysis approach, relying on the Harmonic Balance technique, demonstrates its effectiveness.
