In this paper a time domain formulation of the first and second precursor in

a dispersive materials is reviewed. These precursors are determined by the

susceptibility kernel of the medium, which characterizes the medium in a time

domain formulation. The propagator operators of the fields are corner stones

in the formulation. These operators are then approximated by a pertinent

factorization procedure that defines to the first and second precursors of the

medium. Wave propagation in a biisotropic medium is also treated and the

early time behavior of a transient signal is addressed. Aseries of numerical

examples illustrates the theory.
