Abstract

Electromagnetic metamaterials applied to wireless power transmission (WPT) systems must be placed between two coils to improve the coupling of the system. This takes up intermediate space and is very inflexible in application. In this paper, a superscatterer based on optical transformation theory can amplify the displacement inside the object to some extent. It only needs to be placed at the transmitter or receiver end of the WPT system to improve the coupling of the system. In this paper, a magnetically coupled resonant wireless power transmission (MCR-WPT) system with the topology of series LC at the transmitter end - series LC at the receiver end (S-S type) is modeled on the COMSOL simulation platform. The modeling simulation verifies that the magnetic field of the transmitting coil is significantly enhanced and the mutual inductance of the two coils is significantly increased by adding the super-scatterer. Thus, the coupling degree of the WPT system is enhanced.
