Simulation of three-dimensional finite-difference time domain method on limited memory systems

The authors discuss techniques in the modelling of electromagnetic fields using finite difference time domain (FDTD) methods applied to 80×86-based PCs or limited memory computers. Electrical modelling of structures is currently carried out mainly in the frequency domain using empirical methods or by treating structures as two-dimensional objects. Until recently the application of finite difference methods were applied to supercomputers such as the Cray XMP and Cray II. The power of modern workstations and microcomputers offer large storage area, large memory capacity and fast CPU times. Thus it is now possible for full time domain simulations to be carried out on complex structures on base model workstations and microcomputers
