Progressive Analysis of Electromagnetic Field by Parallel FDTD Algorithm for Big Urban Area 2-D Simulations

Abstract

This paper explores some improvements in the parallel FDTD algorithm using system of linear equations. The objectives are to be able to simulate realistic size models of urban wireless communications using FDTD. The obstacles are the need of large memory and processing time. The previous research has dealt with decreasing the use of memory. From now, the research deals with the improvement of the speed of the algorithm. This is done by using the properties of the impulse response in the system of equations and using it to store pre calculated results that are the most common calculations in FDTD equations.
