摘　　要：对于高功率闭域特点的微波反应腔中电场分布不均的问题,设计一款具有可控超材料的微波反应腔,运用电场分布图示法和电场分布取样的标准偏差分析法研究了负载大小、加热频率、可控超材料参数对加热效率和加热均匀性的影响规律.结果显示,通过适当调整可控超材料参数,可在保证至少97%加热效率的前提下,使加热均匀性提升高达48%.For the problem of uneven electric field distribution in the microwave reaction chamber with high power closed-field characteristics,this paper designs a microwave reaction chamber with controllable metamaterial,uses the electric field distribution diagram method and the standard deviation analysis method of electric field distribution sampling to research the load effects of size,heating frequency,and controllable metamaterial parameters on heating efficiency and heating uniformity.The results show that by way of properly adjusting the parameters of the controllable metamaterial,the heating uniformity can be improved up to 48%on the premise of ensuring at least 97%heating efficiency.
