N2 - We are interested in the amount of power that is absorbed by the eye and surrounding head tissue due to operation of inductive coils which are placed in proximity to the eye. These coils provide power to a retinal implant device wirelessly by means of electromagnetic induction. Using numerical simulation, we computed the specific absorption rate (SAR) due to the coils which are expected to deliver an average of 50 mW of power to the implanted device. By varying the distance of the coil from the eye and its operation frequency, we are able to find the dependence of SAR due to these parameters. From the result, we found that the maximum SAR value to be below 1 mW/kg. This is several orders of magnitude lower than the safety limits set by the Federal Communications Commission.
