Performance enhancement of linear active electronically scanned arrays by means of MbD -synthesized metalenses

Abstract : The key problem of improving the radiation performances or enabling additive functionalities 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, is addressed by means of a suitably formulated Material-by-Design (MbD) approach. The quasi-conformal transformation optics (QCTO) technique and a customized source inversion (SI) strategy are jointly exploited to synthesize enhanced architectures, composed by a metamaterial lens and a tapered version of the original feeding network, able to match the radiation characteristics of significantly larger and/or different (from the original one) apertures. A set of representative benchmark results is reported to assess the effectiveness of the proposed MbD-designed architecture as well as to highlight the existing trade-off between achievable improvements and the complexity of the arising architectural solution.
