Anovel parallel processing synchronization method for observing electric fields in and around PCBs

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. Visualization of an applied gaussian pulse from multiple sources within and outside a PCB are shown and the techniques used to determine the system characteristics are discussed in the paper
