Abstract

An efficient method for the analysis of ultra-wideband (UWB) electromagnetic pulses propagating through dispersive media is indispensable in applications involving UWB radar systems. Closed-form solutions have been obtained for the fields associated with transient sources radiating into lossless plasmas and waveguides (see [1] for historical references). Recently, Dvorak [2] demonstrated that contour integration techniques can be used to analytically evaluate the inverse Fourier transform representation for the potential associated with a continuous-wave transient pulse propagating in a waveguide. Dvorak and Dudley later extended the analysis to the problem of a double-exponential pulse propagating through a simple cold plasma [1].
