This work focus on estimating the RF-induced deposited power at the multi-electrode array of cortical implant (CorTec GmbH, Germany) by means of lead electromagnetic models (LEM). To develop the LEM for such a complex structure, we computed the transfer function for each of the electrode and generated a set of artificial tangential electric fields for validation of the LEM. The transfer functions and the tangential electric fields along the leads are then used to develop the LEM which can estimate the deposited power at the electrode array for an arbitrary lead pathway.
