    "abstract": "Ultra-wideband (UWB) electromagnetic pulses of nanosecond duration, or\nnanopulses, are of considerable interest to the communications industry and are\nbeing explored for various applications in biotechnology and medicine. The\npropagation of a nanopulse through biological matter has been computed in the\ntime domain using the finite difference-time domain method (FDTD). The approach\nrequired existing Cole-Cole model-based descriptions of dielectric properties\nof biological matter to be re-parametrized using the Debye model, but without\nloss of accuracy. The approach has been applied to several tissue types.\nResults show that the electromagnetic field inside a biological tissue depends\non incident pulse rise time and width. Rise time dominates pulse behavior\ninside a tissue as conductivity increases. It has also been found that the\namount of energy deposited by 20 $kV/m$ nanopulses is insufficient to change\nthe temperature of the exposed material for the pulse repetition rates of 1\n$MHz$ or less.",
