The effect of suppressing electromagnetic emission from a printed circuit board (PCB) by using ferrite plates is investigated. The PCB is composed of a stripline terminated with an open, a short or a 50Ω load and an infinite ground plane or finite ground plane. The frequency dependent finite different time domain (FD-FDTD) method is used for the numerical analysis. The calculated results show that a strong suppression effect is achieved when the ferrite plate is located at the position where the magnetic field density is relatively high. In the case of the PCB with the finite ground plane, it is effective to locate another ferrite plate under the ground plane to suppress the radiation from the ground plane of the PCB.
