Influence of Diffuse Reflection on Field Uniformity in Electromagnetic Interference Testing Chamber

The evaluation method of reverberation chamber performance, the function and working principle of mechanical stirrer are described. The effect of diffuse reflection on the uniformity of field intensity in mechanical stirring reverberation chamber was analyzed by electromagnetic simulation software. The simulation results show that the introduction of diffuse reflector can improve the field uniformity of reverberation chamber, and the effect depends on the design and number of diffuse reflector surfaces.
