A metasurface antenna can be configured to focus a paraxial beam, such as a Gaussian beam, on a target within a Fresnel zone region. The focused beam can be used to wirelessly deliver power to the target. In one embodiment, the target is one of a plurality of targets, and the metasurface antenna can be configured to focus a respective plurality of paraxial beams on the plurality of targets.
