Scattering Theory for dissipative and time-dependent systems has been intensively studied in the last fifteen years. The results in this field, based on various tools and techniques, may be found in many published papers. This monograph presents an approach which can be applied to spaces of both even and odd dimension. The ideas on which the approach is based are connected with the RAGE type theorem, with Enss' decomposition of the phase space and with a time-dependent proof of the existence of the operator W which exploits the decay of the local energy of the perturbed and free systems.

The importance of understanding radio wave propagation increases as radar and communication systems become more complex, i.e. digital systems, frequency adaptive systems, spread spectrum systems, etc. Increasingly wider frequency bandwidths are used in modern military systems.
