Proceedings of an international conference held October 1992, at the Microwave Research Institute, Brooklyn, New York. The conference topic was chosen because of the steadily increasing importance of time domain techniques and applications, and also because of the general trend toward wider signal bandwidths, culminating in ultra-wideband, short-pulse electromagnetics. Contributors treat cutting edge issues both analytic and numeric that confront electromagnetic wave modelers in diverse natural and manmade environments in response to new technologies, system requirements, and recent developments in data processing.
