“Good-but-Imperfect” electromagnetic reverberation in a VIRC

Novel theoretical probability density functions (PDF) of electromagnetic fields inside reverberation chambers operating in a “good-but-imperfect” regime have been recently reported. The present work reports on the application and assessment of these PDFs using a non-conventional type of reverberation chamber, namely the Vibrating Intrinsic Reverberation Chamber (VIRC). A vector network analyzer was used in order to measure the complex field components. An electrically short dipole antenna was used as a receiving antenna. Five thousand frequency points were taken ranging from 200MHz (undermoded regime) to 4 GHz (overmoded regime), so one measurement every 760 kHz was performed. For each frequency, 200 samples of the real and imaginary part of the field were measured. Measurements confirm the fact that the novel PDFs are able to describe the occurrence of anomalous statistics in the VIRC.
