Wave propagation speed or velocity of propagation (VoP) of a transmission medium is ratio at which the wavefront of the signal passes through the medium to the speed of light in vacuum. For example, copper has a wave propagation speed ~0.951. What is a wave propagation speed through a living tissue such as for example, muscle, liver or brain? Flesh and biological tissue in general are heterogeneous. So one can assume that in this case current propagates through the movement of ions and charged molecules resulting in low conductivity. To avoid discussion of nonlinear effects such as carbonization etc., let us use as an example, an electrocution event at moderate current densities (low electrical field). Most probably we must take under consideration some (micro) capacitances and perhaps inductances (?) to account for the effect? Anyone knew the range of VoP values for living tissue? References?
