Influence of reverberation chamber loading on extreme field strength

Electronic equipment is often susceptible to the maximum field strength instead of the average field strength. The difficulty of finding the absolutely maximal field strength inside a reverberation chamber arises from the troublesome link between the statistical and deterministic approach. The established theoretical models propose interesting solutions to this problem but require more experimental verification. This paper focuses on the experiments utilizing a Vibrating Intrinsic Reverberation Chamber (VIRC) as a tool allowing for extended real-life field analysis. The randomness of movement of flexible walls of a VIRC is exploited by conducting long, 1 hour measurements. Statistical analysis of the data is conducted to evaluate the maximal and average, and their ratio for different chamber loads and quality factors.
