Abstract: This paper describes a parallel three-dimensional finite difference time-domain (FDTD) code for electromagnetic field simulation that has been developed for the Connection Machine (CM-2). The CM-2 is briefly discussed. Then the FDTD method is reviewed using a one-dimensional example, and the extensions required for the 3-D case are outlined. The parallelization of the FDTD method is considered, and a simple analytical timing model is derived. This model predicts the efficiency of the parallelized algorithm as a function of grain size. Some specific points relating to the implementation of the parallel FDTD algorithm in Fortran- 90 on the CM-2 are discussed. Timing data for the parallel 3-D FDTD code measured on a CM-2 is presented and compared qualitatively with the theoretical model. These results are then put into perspective for a particular computational electromagnetics problem, viz, the development of software tools for full-wave modelling of 3-D optical devices. Finally, we draw some conclusions about this work. [ABSTRACT FROM AUTHOR]
