Evaluation of the Split Stirrer in Reverberation Chamber

Reverberation chambers are used widely for EMC testing in industry. The design of the mechanical stirrer should be considered artistically. This paper introduces a split stirrer design, the simulation result shows the good performance of this stirrer and a prototype chamber is built according to the simulation. The critical parameters of the reverberation chamber are analyzed in detail. Four calibrations are processed to evaluate the testing repeatability and validate the performance of the split stirrer
