摘要: Average absorption cross section can be measured in a reverberation chamber with an uncertainty estimated from the number of independent samples transfer function taken during measurement. However, current model does not account loading effect object being or presence nonstochastic energy chamber, as characterized by Rician K -factor. Here, for cross-section measurements has been extended to include both these effects case stepped mechanical tuning paddle and frequency tuning. The formula applied predict range over which made defined relative given geometry, using simple models quality-factor validated on set absorbing cubes different sizes compared Mie Series calculation sphere equivalent surface area. error is particularly utile design chambers experiments across wide application areas.
