  • Abstract
    Pulse excitation in FD-TD provides multifrequency results with a single run of the code. The introduction of the Frequency Dependent FD-TD ((FD)2-TD) has also recently provided a means to deal with dispersive materials on condition that they had a first order permittivity. The authors present a multirelaxation approach to widen the (FD)2TD applicability to materials with more complex permittivity such as biological tissues
