Analysis of UWB pulse propagation in multi-layer and dispersive geomaterials with AH FDTD method

To study the Ultra-Wideband (UWB) Pulse propagation in multi-layer and dispersive geomaterials, we use the unconditionally stable AH FDTD method for analysis in this paper. This method breaks through the nature of the stability condition, while avoiding convolution process, which is an efficient numerical simulation method. Different pulses, mediums and geotechnical structures are considered and investigated, which produced a series of constructive results for protection projects.
