摘要

本文介绍了一种在微波腔内配置工作频率为2.45 GHz的有源频率选择表面(AFSS)来提高微波加热均匀性的有效方法。该方法通过改变嵌入在AFSS上不同位置的p-i-n二极管的开/关状态,实现了微波腔内电场的重新分布。模拟表明,通过二极管状态控制,不同加热样品的加热均匀性提高了36%以上。为了验证该方法,定制了一个微波加热系统来进行温度测量。仿真结果与实验结果吻合较好,验证了该方法的有效性。

Loading an Active Frequency Selective Surface in Microwave Cavities to Enhance Heating Uniformity
This letter introduces an effective method to enhance microwave heating uniformity by equipping an active frequency selective surface (AFSS) working at 2.45 GHz within microwave cavities. By changing the on/off states of p-i-n diodes embedded at different locations on the AFSS, the proposed method achieves the redistribution of the electric field in the microwave cavity. Simulations demonstrate an increase of over 36% in heating uniformity across different heated samples through diode state control. To validate this method, a microwave heating system is customized to conduct temperature measurements. Good agreement is achieved between simulations and experiments, verifying the validity of this method.
