Circuit model, FDTD, high voltage, human body, lightningAbstract
In the present paper, a simplified lumped element human body, stroked by a lightning touch volage, is designed and analyzed using the finitedifference time-domain (FDTD) method. The extracted results are compared with an electronic circuit simultor validating our numerical method. Moreover, other touch voltage scenarios are investigated, measuring and comparing the current that flows through different body parts. Additionally, the induced current to a human body, being in the vicinity of a lightning stroked object, is accurately calculated through the FDTD algorithm. The inability of the circuit modeler to simulate non-contact configurations proves the necessity of our numerical algorithm, while the possibility of the electric discharge effect is introduced.
