Abstract

A composite artificial magnetic conductor (AMC) surface with magneto-dielectric substrate is presented for wide band radar cross section (RCS) reduction. It is shown that using of magneto-dielectric substrate can increase the in-phase reflection bandwidth of AMC structures. The composite surface consists of two kinds of AMC cells that operates at different resonance frequencies. The phase difference between these two different AMC are tuned to be close to 180 degree  over a wide bandwidth so that the reflections from them cells cancel each other. The results show that RCS reduction more than 13 dB was achieved with a 93% bandwidth.
