FDTD applications to electromagnetic interference and shielding

The finite difference time domain method (FDTD) is applied to two electromagnetic interference (EMI) problems. The technique is used to simulate fields to wire coupling. Two types of excitation are used in this simulation: a plane wave excitation and a dipole antenna. The effect of the shield (enclosure) presence on the strength of penetrated field is studied via the calculation of the shielding effect. The results obtained confirm the capability of the FDTD technique for modeling EMI problems.
