SAR in the human body by a wireless telemetry system for a retinal prosthesis

In this work, the 3D explicit FDTD method in a D-H formulation similar to (D. Sullivan, 2000) has been used to calculate the electromagnetic fields in the human head due to the operation of the wireless link at 10 MHz of the proposed retinal prosthesis system. The specific absorption rate (SAR) was obtained from the E-field values to compare with safety standards.
