A numerical method for the computation of induced currents inside 3-D heterogeneous biological bodies by ELF--LF electric fields.
A numerical technique, based on the combination of surface-charge integral equations (SCIE) and an impedance network method, has been developed to compute internal electric fields and currents inside 3-D heterogeneous biological bodies with arbitrary grounding impedances induced by ELF-LF electric fields. The method has been applied to a biological concentric-sphere and the numerical results agree well with an existing analytical solution. Numerical results of the induced current inside a simplified heterogeneous model of the human head computed by this method are also presented.
