摘要

This letter presents a tunable absorbing composite that integrates a varistor-diode-based ultrathin impedance layer into a lightweight sandwich structure for broadband and continuously programmable radar cross section (RCS) control. A theoretical equivalence model is established and reveals that the tunable layer emulates multiple resistance states. Based on thismechanism, the metasurface achieves amplitude-coded RCS control through the spatial arrangement of the 40Ω, 60Ω, and80Ωresistive states, in contrast to conventional phase-coded approaches. Experiments verify flexible up to 10 dB RCS reduction over 6 GHz to 13 GHz, demonstrating a scalable route toward adaptive electromagnetic protection materials.
