Prediction of electric fields in and around PCBs - 3D Finite-Difference Time-Domain approach with parallel processing

The authors have taken the 3D FDTD approach to simulate the propagation of electrical signals within and around 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. The authors have further demonstrated the use of parallel processing to reduce simulation time. Visualisation of an applied gaussian pulse from multiple sources within and without a PCB are shown and the techniques used to determine the system characteristics are discussed in this paper.
