Eleven Channel Retrodirective Metasurface Based on the Combination of the Generalized Phase Law and Impedance Modulation

摘要

In this paper the design of a retrodirective meta-surface for multiple incident angles is proposed. The design methodology is based on the combination of the generalized phase law of reflection and the implementation of the phase impedance modulation for non reciprocal metasurfaces. An eleven channel retodirective metasurface has been designed and demonstrated. The monostatic radar cross section (RCS) has been calculated to determine the performance of the metasurface design at the desired angles of incidence.
