Abstract
This work presents an innovative material-by-design (MbD) technique for the improvement of the radiation features (in terms of beam-width, directivity and side-lobe level) of existing linear scanned arrays. The developed strategy exploits a suitably customized quasi conformal transformation optics (QCTO) technique to synthesize meta-material radomes with reduced anisotropy as well as a source inversion (SI) strategy in order to let the original array mimic the radiation performance of significantly larger apertures. Some numerical results are presented ad discussed in order to validate the effectiveness of the MbD approach and its suitability to improve the radiation characteristics of linear arrays.
