超材料吸波体发展及在隐身技术中的应用前景

Development of Metamaterial Absorbers and Its Application Prospect in Stealth Technologies

超材料研究从提出至今历经20余年,得到了突飞猛进的发展,其中,超材料吸波特性是研究热点之一。针对此研究热点,简述了超材料吸波体的提出,综述了超材料吸波体的发展,重点介绍了几种基本类型的超材料吸波体,如加载集总元件的超材料吸波体、多单元或多层结构超材料吸波体、多类型材料复合超材料吸波体,最后展望了超材料在隐身技术中的应用前景,并给出了超材料隐身技术走向实用化所面临的若干挑战及发展建议。

The research on metamaterials has developed greatly since it was put forward more than twenty years ago,and the absorbing property of metamaterials is one of the research hotspots.Aiming at this,the proposal of metamaterials absorber is briefly introduced,the development of metamaterials absorber is summarized,and several basic types of metamaterials absorber are emphatically introduced,such as the lumped elements loaded metamaterial absorber,multi-unit or multi-layer metamaterial absorber,multi-type materials composite metamaterial absorber.Finally,the application prospect of metamaterial in stealth technologies is discussed,and some challenges and suggestions for the practical application of metamaterial in stealth technologies are also given.
