Abstract:Frequency Selective Surface (FSS) microwave transparent materials are the concentrated expression and successful practice of pursuing a structure-function integration of microwave transparent materials for a long time. With the increasing performance requirements of antennas and communication systems to omnibearing wave transmission, broadband wave transmission, frequency selective wave transmission, stealth, etc., this technology becomes a new hot spot in the research of microwave transparent materials, and has a wide range of applications in the fields of military and civilian products. A ceramic-based FSS microwave transparent material technology is proposed in accordance with the development of high-temperature and high-performance radome, which is of great significance to the sustainable development of microwave transparent material technology. This paper analyzes the current research needs of ceramic-based FSS microwave transparent materials, introduces the current research status of domestic ceramic-based FSS microwave transparent materials, and prospects for its application prospects.
