Measurement of Dielectric Properties of Materials in Millimeter-Wave Frequency Range

  • 摘要: 系统地开展了毫米波频段材料复介电常数的测量方法研究。基于自由空间法采用两步校准方法和时域选通技术,实现了75~110 GHz宽频范围内材料介电特性的测量表征,并基于准光Fabry-Perot谐振原理,研制具有高品质因数的开放式谐振腔,利用高斯波束理论建立了材料介电特性的反演模型,尤其适用于低损耗介质材料的准确测量。通过对比聚氯乙烯(PVC)与熔融石英材料的测量结果,验证了两种测量方法的一致性。此外,针对多层材料提出了去嵌入测量算法,实现了液晶材料各向异性介电常数的表征。
