A two-step quasi-conformal transformation (QCTO) approach is exploited in order to synthesize meta-material coverings of the conformal arrangements in order to restore their reference free-space radiation features. Moreover, a source inversion (SI) strategy is applied in order to reduce the number of radiators, by synthesizing a new set of excitations of the final conformal architecture. Some numerical results are presented in order to assess the effectiveness as well as the current limitations of the proposed MbD synthesis methodology. date: 2018 publisher: ELEDIA Research Center - University of Trento referencetext: G.
