Abstract
In this letter, an electromagnetic stealth composite superlattice-type structure based on indium tin oxides (ITO) resistive film and frequency selective absorber (FSA) is proposed for radar cross section (RCS) reduction. It exhibits impressive ultra-wideband performance with absorption of more than 85% (RCS reduction 8.2 dB) spanning from 0.94 to 23.2 GHz (relative bandwidth 184.8%). The proposed absorber is also polarization-insensitive and has angular incidence stability up to 45° and 60° for TE and TM polarizations, respectively. Additionally, it demonstrates excellent miniaturization characteristics, with a cell size of only 0.15λL × 0.15λL × 0.09λL, which provides a technical solution for research and application in related fields.
