Abstract :
In this work, the; synthesis of an artificial lens comprising 25 metallic, lamellas is presented. The synthesis of the artificial lens relies entirely on numerical methods. The lens is new in the sense that its reflection of the incident cylindrical wave is low (less than -28dB) while providing the desired csc2t? elevation pattern for air surveillance applications.
