Electromagnetic Exposure on Human Phantom Model in Time-Reversed Wireless Power Transmission System

In this paper, the electromagnetic exposure effects on human body phantom model is described. The wireless power transmission (WPT) system consisting of transmitting array on the top and bottom of the room and the mobile receiving antenna at the center is operated by using time-reversal (TR) technique. The power transmission efficiency (PTE), the power loss in human body, and the specific absorption rate (SAR) level are simulated for a TR WPT system when human body phantom is considered. In addition, TR array and BF (Beam forming) array are compared in terms of the PTE and the electromagnetic effects on the human body.
