Temperature uniformity of temperature-control type microwave absorbing box

This paper studies a small microwave absorbing box,using the TD software to simulate thetemperature of the box and the heat flux uniformity of the antenna,and based on the results of the simulation,thetemperature control circuit and strategy are designed.The temperature control capability of the box is validatedthrough the simulation test which shows that by controlling the temperature of the microwave absorbing boxreasonably,the heat flux uniformity can be kept within5%.
