Abstract
With the increasing prevalence of multi-band detection technologies, military equipment and weapons face heightened risks of exposure to enemy detectors, posing significant challenges to stealth capabilities. This paper proposes a multispectral stealth metamaterial (MSM) designed for cross-band stealth applications in laser, infrared, and radar domains. The device integrates a one-dimensional photonic crystal (1D-PC) and a radar-absorbing metamaterial (RAM), achieving a low specular reflectivity (average value of 0.25) across the 8–14 μm range, over 98 % absorption at 10.6 μm, and more than 90 % absorption efficiency within the 7.5–18 GHz radar band, while simultaneously suppressing high emissivity in the infrared band. A 10 × 10 cm2 sample was fabricated and tested, demonstrating the device’s multispectral modulation performance. This work provides a novel approach to multispectral modulation and thermal radiation management, offering potential advancements in stealth technology.
