摘要
该文给出了暗室高功率微波承载能力的评估方法及提高微波功率承载能力的办法措施:采用近场和远场方法进行计算评估,针对不同种类吸波材料选取合适的安全系数,确保暗室使用安全。这种设计思路在多个高功率承载暗室工程中得到了成功应用。文中首次提出了吸波材料微波功率疲劳损坏概念,对确保暗室微波功率承载使用安全具有很好的指导作用。
In this paper,the evaluation method of the high power microwave carrying capacity of the anechoic chamber and the measures to improve the microwave power carrying capacity are given: the near-field and far-field methods are used to calculate and evaluate,and the appropriate safety factor is selected for different kinds of absorbing materials to ensure the safety of the anechoic chamber.This design idea has been successfully applied in a number of high-power load anechoic chamber projects.The concept of microwave power fatigue damage of microwave absorbing materials is put forward for the first time,which has a good guiding role in ensuring the safety of microwave power bearing in anechoic chamber.
