短脉冲激励的混响室设计
Design of reverberation chamber excited by short pulse
摘要
Abstract
According to the distributions of electromagnetic field in an ideal resonator, the parameters affecting the field distribution were summarized firstly. Then the model of reverberation chamber(RC) was designed according to accustomed rules and special standards to judge the field uniformity in this kind of RC were also established. Lastly the influences of the cavity shape and the method of source stirring on the characteristics of the electric field in the RC were analyzed. The standard deviation of e-lectric field in the RC is reduced by 0. 4 dB by moving the source continuously along ten positions. The numerical simulation shows that the usage of the complex resonator is effective to improve the homogeneity of the field and validates the feasibility of moving the source continuously in the RC excited by short pulse to improve the field uniformity.关键词
