摘要：

Microwave power standard adopts calorimetry techniques to calibrate the effective efficiency of the thermistor mount. Correction factor is the key of calibration thermistor mount. The microwave power standard mainly adopted short-circuited mode to determine the correction factor so far, but it must consider the effects of microwave power absorbed by short plate to thermopile, so the method that how to get the power dissipated in the short plate is the key to calculating correction factor and its uncertainty. This paper presents a new method based on electromagnetic field theory to consider the short-circuit dissipation power. A detailed analysis of its superiority over the traditional method is shown. It reduces the uncertainty of the correction factor reasonably, in other words, reduces the uncertainty of the microwave power standard.
