摘要
给出用于毫米波频段精确测量介质片复介电常数的准光开放腔系统的误差分析,说明了近似理论引起的误差和被测量提取不准引起的误差。推导了相关的公式,给出了分析的数值结果和测量结果。
Errors analysis of quasi optical open cavity, which is used to measure the complex die- lectric constant of the dielectric plate accurately, is presented. The errors from the approximating theory and the errors due to the measurement system and measurement process are described. The formulas are deduced, and the simulation results and measurement results are presented.
