Abstract
Described embodiments include a system, method, and apparatus. A system includes an antenna comprising a sub-Nyquist holographic aperture configured to define selectable arbitrary complex radiofrequency electromagnetic fields on a surface of the antenna. A path analysis engine tests power transmission pathways from the antenna to a target device located in an environment within a space radiateable by the antenna. The environment includes a human being. An optimization circuit selects responsive to the tested power transmission pathways a power transmission regime. The regime includes an electromagnetic radiation pattern shaped to transfer radiofrequency electromagnetic power from the antenna to the target device without exceeding a radiation exposure limit for humans. A gain definition circuit selects a complex radiofrequency electromagnetic field implementing the selected power transmission regime from the at least two selectable, complex radiofrequency electromagnetic fields. An antenna controller defines the selected arbitrary complex radiofrequency electromagnetic field in the sub-Nyquist holographic aperture.
