Abstract

Ultra Wideband (UWB) systems have applications that continue to impact us in new ways. Maxwell's equations solvers seem to be well positioned choices to develop these new applications and among them FDTD is generally accepted as the most widely used. Amongst the implicit iterative methods used under FDTD is the Crank Nicolson (C-N) method. A brilliant approximation of this method, called the Alternating Segment Crank Nicolson (or ASC-N) FDTD method, trades an overall faster simulation time for a little loss in accuracy. This is because it lends itself to parallelism.The implementation issues are discussed as well as the parameters that cause a deviation of the simulation results from the expected results. Overall, it is demonstrated in this thesis that the ASC-N method has promising results as a solution to Maxwell's equations.
