| 摘 要： | 基于传输线等效理论,设计了含有源频率选择表面(active frequency selective surface,AFSS)的三层可调复合吸波体,第一层是表面层,为AFSS衬底;中间层是AFSS层,由频率选择表面(frequency selective surface,FSS)和PIN二极管阵列构成;第三层是介质层.反射率测量结果表明,通过调节PIN二极管阵列偏置电压可以动态调节吸波体反射特性,在偏置电压为5 V时,可获得最佳吸波性能,在5—15 GHz和5.3—13 GHz频段分别可获得-8 dB和-关键词：频率选择表面复合吸波材料反射率PIN二极管

| Abstract: | Based on the equivalent transmission line theory,a three-layer tunable composite absorber with active frequency selective surface (AFSS) is designed.The first layer is an AFSS substrate.The middle layer is an AFSS,which is composed of a frequency selective surface (FSS) and a PIN diode array.The third layer is an insulator.Reflectance measurement shows that the reflection characteristic of the absorber can be dynamically adjusted by adjusting the bias voltage of the PIN diode array.When the bias voltage is ... |
