%X In this work, a novel Material-by-Design (MbD) synthesis approach is proposed to address the conformal miniaturization of linear antenna arrays. The developed methodology exploits as a first step a quasi-conformal transformation optics (QCTO) algorithm to design a meta-material radome able to restore the desired radiation features of the radiating system once it has been made conformal to an arbitrary surface. Moreover, a second step based on a source inversion (SI) strategy is exploited in order to miniaturize the conformal architecture, by reducing the number of required radiators in the final conformal arrangement. Some numerical results are shown based on full-wave analyses in order to validate the effectiveness, as well as the current limitations, of the proposed design technique.
