Abstract
This work deals with the problem of improving the radiation performances of linear active electronically scanned arrays (AESAs), without increasing the number of radiating elements nor requiring a re-design of the radiators and/or the feeding network. The problem is addressed by means of an innovative Material-by-Design (MbD) approach based on the quasi-conformal transformation optics (QCTO) technique and a customized source inversion (SI) strategy. The synthesized architectures are composed by a metamaterial lens and a tapered version of the original feeding network, able to match the radiation characteristics of significantly larger apertures. Some preliminary results are reported in order to validate the effectiveness of the proposed MbD approach.
