Emerging technology for transient and broad-band analysis and synthesis of antennas and scatterers

Due to some applied problems of recent interest significant effort has been devoted to developing the technology of the transient and broad-band electromagnetic response of various objects such as antennas and scatterers as well as the production mechanisms for such transient fields. This paper addresses the various types of approaches which have been used for understandiag such transient/broad-band properties. While initially various approaches aid in analysis of such fields, in some cases other properties of the approaches lead to more powerful results such as synthesis of transient/broad-band properties.
