Temporal discretization for UWB systems in three dimensional alternating-direction implicit finite difference time domain method

[摘要] References(8)Cited-By(1)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.
