The quasi-conformal transformation optics (QCTO) approach is exploited to design an enhancing meta-material lens that is able to focus the radiated field of the original antenna. Moreover, a source inversion (SI) strategy is adopted to properly set the array excitations in order to match the radiation characteristics of significantly larger apertures. Some preliminary numerical results are reported and discussed. date: 2018 publisher: ELEDIA Research Center - University of Trento referencetext: G. Oliveri, G. Gottardi, F. Robol, A. Polo, L.
