A combination of transformation optics and surface impedance modulation to design compact retrodirective reflectors

Résumé

This study proposes a new approach to flatten retrodirective corner reflectors. The proposed method enables compact reflectors via Transformation Optics (TO) combined with Surface Impedance Modulation (SIM). This combination permits to relax the constraints on the anisotropic material resulting from the TO. Phase gradient approach is generalized to be used within anisotropic media and is implemented with SIM. Different reflector setups are designed, simulated and compared for í µí±“ í µí±œí µí± = 8í µí°ºí µí°»í µí± § using ANSYS ® HFSS ® in order to validate the use of such a combination.
