摘要

矢量网络分析仪的偏移短校准方案需要精确了解偏移线的传播常数。根据第一性原理计算传播常数的困难，提出了一种间接确定传播常数的方法。在50 GHz时，对于长度为13 mm的2.4mm偏置短，该方法在线性s参数上的精度至少提高了0.013。

The propagation constant of coaxial offset shorts with rough surfaces

Offset short calibration schemes for vector network analyzers require the exact knowledge of the propagation constant of the offsetting lines. The propagation constant is difficult to compute from first principles and thus a method to indirectly determine the propagation constant is presented. At 50 GHz, the method achieves improvements of accuracy of at least 0.013 in linear S-parameters for a 2.4mm offset short with length 13 mm.
