Abstract :
Herein we analyze the propagation of a ultrawideband trapezoidal pulse through human tissues. This analysis indicates that the frequency dispersive propagation implies larger power levels in the propagated electric field which lead to review the definition of the exposure limit for ultrawideband signals.
