Near-field shaping at microwave or millimeter wave frequencies is an emerging field of study, able to accelerate a variety of technologies. Applications from sensing to medical imaging will benefit from accurate near-field shaping methods. In this communication, the use of convex optimization to shape the near field of a flat radiating aperture is investigated. The proposed approach, that is known to provide optimal solutions, is compared to existing near-field shaping methods. © 2017 Euraap.
