摘　　要：提出的频率选择性透波吸波（FSTA）复合结构,是一种在保证天线正常工作性能的前提下,实现对带外电磁波吸收的新技术。该技术具有隐身频带宽,自身结构强度强,电子设备电磁兼容特性高等优势。分析了一些典型频率选择表面（FSS）单元的等效电路模型,推导出了FSTA复合材料的等效电路模型,实现了对新型结构的快速定性分析,并得到结构中各参数对结构性能的作用规律。通过仿真优化实现了低频透波高频吸波（LTHA）型电磁结构的设计。The muhi-layer structure with frequency selective transmission and absorption properties is designed in this paper, which is a new technique to absorb out-of-band electromagnetic waves while the antenna is working normally. It has many advantages, such as wide stealth band, strong structural strength and high electromagnetic compatibility of electronic equipment. This paper analyzes the equivalent circuit model of some typical frequency selective surface （FSS） elements, and deduces the equivalent circuit model of the multi-layer structure with frequency selective transmission and absorption （FSTA） properties, in this way we obtain an efficient and quick identification of new structure and the rules of parametersj effects on struetural behavior. By simulation and optimization, we obtain the structure of transmission at low frequency and absorption at high frequency（ LTHA）.
