主要论述频率选择面(FSS)的空间应用。在对多种形式的FSS散射特性进行分析计算的基础上,选择了一种圆环FSS阵列,在C/Ku,S/Ka等频段上进行了数值分析和试验验证,获得满意结果。单层FSS的反射带宽在Ka频段达到17％,此带宽内0°～45°入射角实测的TE、TM波反射损耗最大值约为0.3dB;各个入射角或极化情况的中心频率理论计算值与实测偏差一般为1％～2％;试验样品所采用的材料及工艺均考虑了空间应用要求。
Mainly discusses the frequency selection surface (FSS) spatial application. Based on the analysis and calculation of various forms of FSS scattering characteristics, a circular FSS array was selected and the numerical analysis and experimental verification were carried out on C / Ku, S / Ka and other bands to obtain satisfactory results. The reflection bandwidth of single-layer FSS reaches 17% in Ka band, and the maximum measured TE and TM wave reflection loss at 0 ° ~45 ° incidence angle in this bandwidth is about 0.3 dB. The theoretical calculation of the center frequency of each incident angle or polarization The value and the measured deviation is generally 1% to 2%; the materials and processes used in the test samples take into account the space application requirements.
