摘要
从宽带、低雷达散射截面天线罩的应用和发展出发,对人工电磁结构在带通滤波器应用中的两种主要形式—频率选择表面和超材料,进行了机理、特性以及差别分析,指出了带通型人工电磁结构宽带设计应关注的主要问题和发展技术途径,为基于个性认知的交融及电磁功能结构发展提供指导和参考。
On the basis of the application and development of wideband radome with low radar cross section, the artificial electro magnetic structure is applied on band-pass filter in two forms: the frequency selective surface and metamaterials. The mechanism, characteristics and difference are analyzed. The main problems and technical way of the design of wideband artificial electromagnetic structure are pointed out. The conclusion provides development-direction and reference for electromagnetic structures.
