Application of large-scale electromagnetic numerical methods to model ultra wideband radio wave propagation

The pseudo-spectral time domain (PSTD) method and the local spectral time domain (LSTD) method, two large-scale electromagnetic numerical methods, were applied to investigate ultra wideband (UWB) radio wave propagation. A one-dimensional (1D) initial condition technique was applied and extended in order to use these large-scale methods. Some numerical simulations were used to study the feasibility and efficiency of these two methods. Compared with the UWB measurement methodology, the theoretical simulations may be more convenient, practical and helpful in link-budget analysis of UWB wireless communication.
