摘要
利用共面波导的S参数建立了一种计算亚太赫兹频率下材料介电常数实部和虚部的模型,并给出了该模型的详细推导过程和应用实例。基于该模型,利用测试得到的共面波导的S参数计算了200GHz下衬底材料的介电常数,计算值与理论结果相符。建立的模型可广泛应用于各类材料在亚太赫兹频段介电性能的表征。
This study proposes a model to measure the real and imaginary parts of the permittivity of a dielectric material using the S -parameters of a coplanar waveguide (CPW),and discusses the detailed derivation and application of the proposed model.Based on this model,the permittivity of the substrate material is calculated at 200GHz using the measured S-parameters of the CPW.The calculated result agrees well with the theoretical value. The proposed model can be employed to characterize the dielectric properties of many materials within the subterahertz frequency regime.
