Abstract

Abstract

With the rapid development of military optoelectronic technology, the role of stealth technology in modern combat systems is becoming more and more important, among which, stealth materials are crucial to improve stealth performance. We focus on infrared stealth materials and review the research progress of domestic and foreign infrared stealth materials from three aspects including single-band infrared stealth, multi-band compatible infrared stealth, and dynamic infrared stealth, and provide an in-depth analysis on the large-area flexible processing methods for micro-nano structures. The main problems of current infrared stealth materials are summarized and the future development trend is foreseen. In the future, to achieve high-performance stealth functions, new infrared stealth materials will further develop in the direction of high strength, large area, flexibility, and intelligence.

Overview

Overview

With the rapid development of military optoelectronic technology, the role of stealth technology in modern combat systems is becoming more and more important, in which stealth materials are essential to improve stealth performance. Infrared stealth is to tune the infrared radiation signal characteristics of the target to become the smallest difference from the background. The target will be invisible in the background and can not be identified through the infrared imaging equipment.

Starting from the background of infrared stealth technology, we introduce the classification of stealth technology and the progress of domestic and foreign infrared stealth materials from three aspects including single-band infrared stealth, multi-band compatible infrared stealth, and dynamic infrared stealth, and provide an in-depth analysis on the large-area flexible processing methods for micro-nano structures. Compared with single-band infrared stealth, multi-band compatible infrared stealth based on the photonic crystal, Fabry-Perot cavity structure, and metasurface, dynamic infrared stealth has higher freedom of spectral modulation. With the development of advanced micro-nano processing technology, metasurface is expected to become the first choice for new infrared stealth in the future due to its ultra-high freedom spectral modulation, ultra-thin subwavelength structures, etc. In addition, we have conducted an in-depth analysis of flexible processing methods for large areas of micro and nano structures.

Finally, based on the summary and reflection of the research work, the development of new infrared stealth materials will be further prospected. 1) High-strength direction development. In some stealth material application scenarios such as aircraft, vehicles, tanks, and other weaponry, the material will function in extreme environments. Therefore, the new infrared stealth materials have good mechanical properties, high-temperature resistance, corrosion resistance, impact resistance, etc. 2) Large-area direction development. In actual applications, the target to be stealthy is from centimeter-level to meter-level applications, so a large area of new infrared stealth materials is the inevitable trend of future development. 3) Flexible direction development. No matter the stealth target is equipment parts or clothing wear, achieving conformal stealth is a key part of stealth material development. 4) Intelligent direction development. Due to the continuous development and integration of multi-band detection technology and the harsh requirements of the actual environment, the realization of real-time dynamic multi-band intelligent stealth is a major demand for stealth technology.
