Abstract
A simple metallic transmission screen is proposed that is capable of focusing an incident plane wave into a sub-wavelength spot in the near field. The principle of operation is inspired by holographic concepts applied to the near-field. A corresponding design procedure is described and supporting full-wave simulation results are provided.
