研究了用透射/反射法测定复介电常数和渗透率的方法。对介电常数测量的特殊情况进行了详细的研究。鲁棒算法介电常数的测定，消除了在频率对应的整数倍的一半波长的样品中常用程序的不良行为的性质。给出了由散射参数、长度测量和参考平面位置的不确定性引起的误差估计。导出了与参考平面位置和样品长度无关的复介电常数的计算公式
The transmission/reflection method for complex permittivity and permeability determination is studied. The special case of permittivity measurement is examined in detail. Robust algorithms for permittivity determination that eliminate the ill-behaved nature of the commonly used procedures at frequencies corresponding to integer multiples of one-half wavelength in the sample are presented. An error analysis yielding estimates of the errors incurred due to the uncertainty in scattering parameters, length measurement, and reference plane position is presented. Equations for determining complex permittivity independent from reference plane position and sample length are derived.<>
