Over recent years, reverberation chambers have been analyzed by numerical techniques like the method of moments and FDTD. This contribution studies the convergence of the FDTD technique as function of the wall conductivity or introducing a lossy media, and consequently, as function of the cavity factor. By lowering the reflection coefficients of the chamber walls the computation time could be considerably reduced without a significant effect on the field distribution. The fields are strongly correlated when the conductivity of the wall is a hundredth of the copper conductivity or greater, whereas for higher losses the field distribution inside the chamber is not correlated with the other cases.
