abstract: This work presents an innovative Material-by-Design (MbD) technique aimed at  improving the radiation features of existing linear active electronically-scanned arrays (AESAs). Such a performance enhancement (in terms of beam-width, directivity, and side-lobe level) is guaranteed without increasing the number of elements nor requiring the re-design of the radiators and/or feeding network. Thanks to a suitable customization and integration of the quasi-conformal transformation optics (QCTO) technique approach with a source inversion (SI) strategy, the developed methodology enables the synthesis of meta-material enhancing radomes with reduced complexity (in terms of anisotropy indexes) able to let the original array reproduce the radiation performance of larger target apertures. Some representative numerical results are shown in order to validate the effectiveness of the proposed MbD approach, by taking into account the existing trade-off between the achievable boost and the overall cost in terms of complexity of the QCTO-synthesized meta-materials.
