Radar stealth and mechanical properties of a broadband radar absorbing structure

A non-magnetic broadband radar absorbing structure (RAS) composed of glass fiber composite and multilayer frequency selective surface (FSS) films was designed, with subsequently optimizing and manufacturing for radar absorbing and mechanical investigations. The results revealed that the proposed RAS exhibited −10 dB absorption from 8 GHz to 18 GHz at thickness of 3.5 mm, with a substantially broadened absorption bandwidth via dual absorption...
