Abstract

This paper presents the design of an absorptive metasurface suitable for complex-shaped targets, achieving precise control over electromagnetic waves, which has been experimentally validated. The metasurface, with a design thickness of only 0.27 mm, maintains sufficient absorption properties under appropriate curvature conditions to ensure the stealth characteristics of the coated target. Through simulation and experimental validation, this study demonstrates the metasurface's strong resonance characteristics near 11.26 GHz and a reduction of approximately 3 dB in far-field radar cross section (RCS) simulation. The experimental test results are almost consistent with the simulation results, confirming the metasurface's effectiveness in reducing the RCS of actual complex models. The research findings provide strong technical support for the radar stealth research of targets.
