Abstract
In this letter, a vibrating intrinsic reverberation chamber (VIRC) working in mode tuning is designed and fabricated; the designed RC is made of a highly electrically conductive silver fabric. A stepper motor is used to tune the cavity surface step by step along its normal direction, and an RC with vibrating wall is realized. The corresponding relationship between the vibrating amplitude and frequency of use is calculated. A test system is developed and the performance of VIRC is experimentally verified. Measurement results show that the measured E-field samples follow a Rician distribution, and the standard deviation of the space E-field is less than 3 dB, which meets the requirements of statistical uniformity tolerance in IEC 61000-4-21.
