【摘要】 本文提出了一种基于频率选择表面(FSS)的带有透波窗口的吸透一体材料,该材料由加载电阻的吸波阻抗层和通带频率选择表面构成,它对电磁波具有带内透波和带外吸波的特性,在雷达隐身和天线罩领域具有广阔的应用前景。仿真结果表明,所设计的结构在10.5 GHz～12.2 GHz范围内具有透波特性,插入损耗均小于1 dB,其中在11.5GHz处有最小插损0.072 dB。该结构在6.15 GHz～15.6 GHz内反射系数低于-10 dB,其中在6.15 GHz～9.11 GHz和13.27 GHz～15.6 GHz内反射系数和传输系数均低于-10 dB,实现高频和低频同时吸波。更多还原

【Abstract】 This article proposes a frequency selective surface(FSS) based absorption and transmission integrated material with a transmission window.The material is composed of an absorption impedance layer loaded with a resistor and a passband frequency selective surface.It has characteristics of in band and out of band absorption for electromagnetic waves,and has broad application prospects in radar stealth and radomes.The simulation results show that the designed structure has transmission characteristics in the range of 10.5 GHz to 12.2 GHz,with insertion losses less than-1 dB,with a minimum insertion loss of-0.072 dB at 11.5 GHz.The reflection coefficient of this structure is lower than-10 dB within 6.15 GHz～15.6 GHz,and the reflection coefficient and transmission coefficient are both lower than-10 dB within 9.11 GHz～13.27 GHz,achieving simultaneous absorption of high-frequency and low-frequency waves.更多还原
