This paper presents a study of the transmitted power and efficiency of a wireless power transfer system which employs a metamaterial consisting of an array of multiple magnetically coupled resonant inductors. In order to reach the maximum efficiency when the receiving inductor is located at the end of the metamaterial line, the system can be designed and matched simply through the magnetoinductive wave (MIW) theory. The efficiency of this type of systems is analyzed and measured through a 5W prototype built in laboratory, using an inverter. The goal of this paper is to study the effects of changing the termination impedance in the last cell of the metamaterial and improve the system performance for a resonant frequency in the order of hundred kHz.

Abstract
This paper presents a study of the transmitted power and efficiency of a wireless power transfer system which employs a metamaterial consisting of an array of multiple magnetically coupled resonant inductors. In order to reach the maximum efficiency when the receiving inductor is located at the end of the metamaterial line, the system can be designed and matched simply through the magnetoinductive wave (MIW) theory. The efficiency of this type of systems is analyzed and measured through a 5W prototype built in laboratory, using an inverter. The goal of this paper is to study the effects of changing the termination impedance in the last cell of the metamaterial and improve the system performance for a resonant frequency in the order of hundred kHz.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
