Electromagnetic wave propagation in dispersive and complex material with time domain techniques
Author
Summary, in English
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.
