This paper proposes a frequency diverse array (FDA) design approach, based on nonlinear frequency offsets and time-modulated weights, for far-field wireless power transmission (WPT). The objective is to optimize the frequency offsets and weights across the array elements to provide maximum end-to-end energy transfer efficiency (ETE). A set of numerical examples is reported and discussed to validate the effectiveness of the proposed WPT-FDA approach.
