چکیده مقاله:
An ultra-wideband thin metasurface is designed and fabricated to reduce the radar cross-section (RCS) from ۹.۷۲ GHz to ۲۶.۷۷ GHz (۹۳ % bandwidth) more than ۱۰ dB. The proposed metasurface is composed of two different artificial magnetic conductor (AMC) tiles with about ۱۸۰° reflection phase differences to destruct the reflected wave over ultra-wideband frequency. Although the designed tiles have similar unit cell configuration, their reflected phase responses are properly tuned by changing the dimensions. The comparison between the proposed AMC metasurface and some sate of the art references clearly proves the high RCS reduction bandwidth with very low thickness of the designed AMC metasurface rather than the references. The measured results are in good agreement with the simulation ones which prove the idea.
