%X This work deals with the conformal miniaturization of linear antenna arrays. Towards this end, a novel synthesis approach based on the Material-by-Design (MbD) paradigm is proposed. The presented methodology exploits the integration of a two-step quasi-conformal transformation optics (QCTO) approach with a source inversion (SI) strategy. One the one hand, the purpose of the QCTO is to synthesize a meta-material covering that is able to restore the radiation features of the radiating system once its geometry has been matched to an arbitrary conformal profile.  On the other hand, the SI allows to reduce the number of required radiators in the final conformal geometry without introducing visible alterations to the desired radiation features. Some numerical results are shown in order to validate the proposed MbD synthesis approach for the design of meta-material lenses based on spline curves.
