Propagation of UWB Electromagnetic Pulses Through Lossy Plasmas
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been obtained for the fields associated with transient sources radiating into lossless plasmas and waveguides (see  for historical references). Recently, Dvorak  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 .
