摘要：
Reverberation chambers (RCs) are used widely in the electromagnetic measurement area. An RC is designed to have a long reverberation time, generate numerous modes, and provide good field uniformity within the chamber. The purpose of this paper is to describe the design process and measurement of the KRISS Reverberation Chamber (KRC). KRC models with 4.5 m x 3.4 m x 2.8 m dimensions are simulated by 3D numerical simulation software. The field uniformity and correlation coefficient are then analyzed at 200 MHz to obtain the optimized model. The simulation results show good performance in terms of field uniformity and are confirmed by measurement from 200MHz to 1 GHz. The lowest usable frequency (LUF) of KRC was confirmed by field uniformity to be 200 MHz. However, the stirrer correlation coefficient results show good performance above 300 MHz.
