The exploitation of frequency diversity in array systems is theoretically discussed in the literature for wireless power transfer applications, because of the unique capability of energy focusing. In this paper the family of frequency-diverse arrays with logarithmic distribution of the frequency is deeply investigated through an accurate numerical approach: an efficient Harmonic Balance-based simulation is combined with the full-wave description of the array made of eight planar monopoles.

Abstract
The exploitation of frequency diversity in array systems is theoretically discussed in the literature for wireless power transfer applications, because of the unique capability of energy focusing. In this paper the family of frequency-diverse arrays with logarithmic distribution of the frequency is deeply investigated through an accurate numerical approach: an efficient Harmonic Balance-based simulation is combined with the full-wave description of the array made of eight planar monopoles. The obtained results confirm the energy focusing potentiality of these radiating systems, even in presence of their intrinsic time-dependent radiation. A preliminary set-up of the complex control system architecture is presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
