Abstract: We have extended the previously three-dimensional impedance method to parallel implementation for bioelectromagnetic applications. Based on Maxwell’s equation, we deduced the 3-D IM and found the association between the minimum incident wave length and the resolution of human body model. Furthermore, we designed a communication scheme to exchange the border data for processors during iteration by Message Passing Interface (MPI) library and a parallel system was set up. We present the solution of the induced current caused by exposure to power line in visible human body model whose resolution is 3 mm and contend 196×114×626 cells. The results had confirm the validation and effective of parallel IM.

Key words: three-dimensional impedance method (3-D IM), parallel computation system, high-voltage transmission lines
