Parallel processing techniques in EMP propagation using 3D finite-difference time-domain (FDTD) method.

Research Output

The authors have applied the 3D FDTD technique to simulate the propagation of electrical signals on a microstrip antenna using a four-transputer array connected to a 386-based PC. This relates to work currently being carried out into the propagation of very high speed digital pulse in printed circuit boards in high bandwidth systems. Methods have been devised by the authors which reduce the amount of stored data and improve run-time. These methods include subgridding, shielded volume and concurrent processing of the problem. Results have been obtained and rre presented in this paper to show improved accuracy and decreased run-time. An analysis of run-time to the number of transputers in an array for optimum operation has been presented. A trade-off between intertransputer communication of segment boundary conditions and the size of each segment has also been discussed in the paper.
