抄録

The treatment of Ultra WideBand systems in a three dimensional Alternating Direction Implicit Finite Difference Time Domain is given. Unavoidable artifacts caused by insufficient source sampling of UWB signals in ADI-FDTD are described. An empirical approach of determining the appropriate temporal discretization is proposed and verified by numerical experiments.
