A multi-relaxation (FD)/sup 2/-TD method for modeling dispersion in biological tissues

Pulse excitation in FD-TD provides multifrequency results with a single run of the code. The introduction of the Frequency Dependent FD-TD ((FD)/sup 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)/sup 2/TD applicability to materials with more complex permittivity such as biological tissues. >
