Broadband multispectral compatible absorbers for radar, infrared and visible stealth application

Multispectral compatible stealth technology, such as radar-infrared, infrared–visible, and radar-infrared–visible stealth, has been applied in the military field for better defensive capability than single-band technology. Developing low radar cross-section, low infrared radiation energy, and optical transparency compatible stealth materials is promising for the large-scale application of military. In this review, a deep analysis about multispectral compatible stealth technology is presented to understand the various types, the mechanisms and the design principles of different waveband absorbers. Subsequently, recent advances of compatible stealth materials are discussed in detail. Finally, current challenges and future opportunities in this promising field are also proposed and predicted.
