tion of fields as a product of coordinate-dependent and
time-dependent factors. The temporal variations of both media and
fields are given by Fourier expansions. The successes of
radiotechnique provided fertile ground for the dominance of
sinusoidal waves in wave physics. This approach proved to be a
powerful the oretical tool, since researchers were dealing with
long trains of slowly varying quasi-monochromatic waves. However,
the success of this concept and the stan dardizability of related
designs engendered a peculiar psychological hypnosis of Fourier
electromagnetics, which took over as a model for wave phenomena in
such cross-discipIlnary areas of physics as optics and acoustics.
Yet in providing a description of alternating fields, the
presentation of such fields in terms of traveling waves with
frequency wand wave number k is not a law of nature. One can see
that such a presentation is not even a logical corollary of
Maxwell's equations. What is more, this approach has become
inadequate today for the analysis of fields excited by ultrashort
transients in continuous media."
