Abstract
In this work, an innovative Material-by-Design (MbD) methodology is proposed to improve the radiation features of a linear active electronically-scanned array (AESA) without increasing the number of elements nor requiring the re-design of the radiators and/or feeding network. 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.
