Abstract

- Recently, there have been a lot of inventions and development in the field of wireless power transfer (WPT), which has increased the need for WPT systems with high power transfer efficiency (PTE) and longer transmission distances for end users. However, several of the presently accessible WPT systems exhibit restricted PTE and transmission range as a result of their utilization of inductive coupling. In addition, the PTE experiences a significant decline as the separation between the transmitter and receiver coils grows while employing this methodology. Hence, this study presents a proposal for the design of inductive WPT using metamaterials (MTMs) to improve PTE through the manipulation of magnetic field refraction. The efficiency and range of WPT can be enhanced by implementing MTMs between the transmit (Tx) and receive (Rx) coils. MTMs possess characteristics such as evanescent wave amplification and negative refractive properties, which hold promises for enhancing PTE. At separation of 70 mm, the use of negative permittivity MTM and double negative MTM results in a significant improvement in PTE, with an increase of 230% compared to the WPT system without MTM implementation. The purpose of this study is to offer a comprehensive understanding of the development of negative and double negative MTM-based WPT systems.
