Abstract

With the rapid development of new photoelectric detection technology and precision guided weapons, the importance of stealth technology in modern warfare is increasing day by day. The current detection technology is mainly based on visible light detection, infrared detection and radar detection. The stealth capability will gradually expand to the ultra-wide spectrum of the merger of infrared and radar. In this paper, the photonic crystal structure is optimized based on the "band gap" principle of the photonic crystal and the characteristics of related materials. At the same time, it is laminated and combined with the wave-absorbing materials in the radar band in order to achieve impedance matching and realize the multi-spectral selective stealth in the visible light/infrared/radar band. This technology can achieve stealth effect in both wide spectrum and narrow band. It can be applied to prevent ground equipment, military aircraft and other military equipment from being detected by visible light/infrared/radar and laser, and effectively enhance its battlefield survivability.
