“…For simulation applications, the chamber walls are commonly regarded as the perfect electronic conductor (PEC) [25,26,27,28], and theoretically the corresponding conductivity in Eq. ( 5) can be set to that of zinc, i.e., σ = 16.7 MS/m.…”

For the simulation or theoretical analysis of reverberation chambers, the conductivity of the chamber wall is commonly used when modeling a reverberation chamber, which is one of the focal points of concern for the electromagnetic compatibility community. If the conductivity is not properly set, the field level formed within a chamber will be different from what is expected. The conductivity can be used to estimate the quality factor. Therefore, we get the appropriate equivalent conductivity by comparing numerical results and experimental results of quality factor. To reduce the dependence on the frequency and the dimensions of a chamber, we proposed an intermediate parameter α-based setting for the conductivity, i.e., 10 kS/m for α < 40, 40 kS/m for 40 < α < 80, and α > 80 for 100 kS/m. The numerical results of the quality factor have been verified by the measurement performed within two reverberation chambers. It is expected that the proposed conductivity setting in terms of α will be a useful way for the simulation or theoretical analysis of reverberation chambers.
