Efficient Method of Optimizing Reverberation Chamber Using FDTD and Genetic Algorithm Method
Keywords:
Field uniformity, finite-difference time-domain, genetic algorithm, reverberation chamber, stirrer, transmitting antennaAbstract
An efficient method combining the finite-difference time-domain (FDTD) method and genetic algorithm (GA) is proposed for the reverberation chamber (RC) optimization. In this method, the GA is utilized to optimize the parameters of RC model built by the FDTD method, such as the stirrer position and stirrer shape. Since the application of GA in the RC optimization and the RC model is automatically varied along with the optimization process, this method improves the accuracy and efficiency of the RC optimization. In addition, the influence of transmitting antenna position on the field uniformity around the lowest usable frequency is also investigated by this method. This method has been verified by comparing with the experiment results.
