Abstract
A novel quasi conformal transformation optics (QCTO)-based approach is introduced for the synthesis of coating meta-lenses that are able to improve the radiation pattern of the covered linear antenna arrays. Thanks to the QCTO technique, the proposed material-by-design synthesis methodology is able to reduce the half-power beam-width (HPBW) and the side-lobe level (SLL) of a given linear array without introducing strong anisotropies in the synthesized meta-material coating lens. Some representative numerical examples are shown in order to assess the effectiveness, as well as the limits, of the proposed MbD method.
