Application of 3D finite-difference time-domain (FDTD) method to predict radiation from a PCB with h
The authors have applied the 3D FDTD technique to simulate the propagation of electrical signals within printed circuit boards (PCBs). This relates to the work currently being carried out into the propagation of very high speed digital pulses in PCBs for high bandwidth systems. Visualisation of an applied Gaussian pulse from multiple sources within and outwith a PCB is shown and the techniques used to determine the system characteristics are discussed.
