Abstract [en]

In this paper, the technique of quasi-conformal transformation optics is utilized to design lenses that can alter the radiation properties of common antennas. The performance of these lenses is simulated using numerical software and analysis shows that the directivity can be increased significantly, or the radiation patterns can be changed as desired. Therefore, using this technique, bespoke lenses can be designed that create complex radiation from simple antenna feed types, for a number of high-frequency applications.
