Abstract :
A novel method to include models of complex apertures into the finite-difference time-domain method is presented. Instead of resolving the geometrical details of the aperture, the aperture is treated as a magnetic dipole. The properties of the magnetic dipole moment are determined using the measured transmission cross section of the aperture. This semi-empirical model permits inclusion of complex apertures in FDTD-simulations. Comparisons between simulated and measured shielding effectiveness of a realistic enclosure are presented.
