On the Use of Frequency-diversity for Efficient Wireless Power Transmission

In this paper a wide and deep analysis of the complex radiating mechanism of frequency diverse arrays (FDAs) is provided, by highlighting the strict relationship between the angle, range and time dependency of the corresponding radiation performance. The capability to focus the signal/power in a prescribed region of the space is obtained at the expense of a tough architectural complexity which makes FDAs a pure theoretical topic, up to now. A solution for the practical exploitation of FDAs for wireless power transfer application is the main goal of this paper.
