A study was carried out to demonstrate that the introduction of an artificial loss mechanism into the solution space may be a viable alternative to extremely large numbers of time steps. By setting the conductivity of the free-space cells to a small value, the transient fields inside the cavity were forced to decay to zero much more rapidly, enabling the accurate Fourier transform of the time-domain fields into the frequency domain.
