Transient analysis of the human body with a mobile phone subject to intense UWB pulses

Self-consistent 3-D FDTD analysis of a bounded-wave EMP simulator with a human model in the presence of a complex electrical environment is performed. The designed EMP simulator could be directly applied to the optimization of EMP for a desired level of the field intensity and risetime in UWB pulsed applications. Using a fine mesh and an Itanium II 160 processor cluster allowed the risetime of 1.4 ns - very close to the experimental design of 1 ns. This study is significantly important for investigating the effects of intense UWB pulses on biological cells. A detailed analysis from the point- of-view of physical understanding the effects of EMP on human tissue is presented. The biological cell of high conductivity i.e. small relaxation time inducing minimum field inside the human body is studied. A detailed picture of electric field and current evolution is demonstrated.
