摘　　要：总结了混响室腔室和搅拌器的设计准则,并依此完成了最低可用频率为400 MHz的混响室腔室和搅拌器的设计。利用FEKO软件对混响室建模,进行场均匀性仿真,计算工作区8个位置的电场,得到场标准偏差。仿真结果表明,设计的混响室性能完全符合标准IEC 61000-4-21的规定,电场均匀性小于3 dB。Design norm of the chamber and the stirrers of reverberation chamber was summarized. The chamber and stirrer of a reverberation chamber, whose lowest useable frequency was 400MHz, was designed with the norm. Model of the reverberation chamber was established with the software FEKO, and field uniformity simulation was carried out. The electric field strength in 8 positions of the workplace and standard deviation of electric field was calculated. The results showed that the performance of the reverberation chamber conforms to the IEC 61000-4-21 standard. The field uniformity is less than 3dB.
