Abstract

The problem of enhancing the radiation features (in terms of directivity and side-lobe level) of an existing linear active electronically-scanned array (AESA) is addressed. A novel material-by-design (MbD) design technique is proposed to synthesize suitably engineered meta-material lenses able to significantly improve the performance of the covered antenna array without increasing the number of elementary radiators nor re-designing the feeding network. Moreover, the synthesized architectures are able to mimic the radiation characteristics of larger apertures without requiring highly-anisotropic meta-materials thanks to the exploitation of a customized quasi-conformal transformation optics (QCTO) technique in combination with a source inversion (SI) strategy. Some numerical results are presented and discussed in order to verify the potentialities of the proposed synthesis technique.
