英文摘要： Electromagnetic metamaterials are artificial materials engineered to have novel concepts and properties proposed in recent years. The presence of metamaterials provides a broad space for people to design controllable permittivity and permeability materials, which also provides a new method to regulate the electromagnetic wave transmission. The wireless power transfer and harvesting (WPTH) is a significant technology for future development of science, technology, and new energy, which has broad application prospects. This project takes the proper access to these two emerging research fields to study the key theories and technologies of an efficient wireless power transfer and harvesting based on metamaterials. On one hand, we will carry out the research on miniaturized metamaterial antennas, superlens, electromagnetic wave concentrator designs, and wireless energy tunneling effect theory. On the other hand, we will give an in-depth insight into the mechanism of magnetic resonance wireless power transfer and RF micro-energy harvesting. Finally, we will develop the integrated technology research of metamaterial-based antennas and structures with the wireless power transfer and harvesting system. The project aims to solve the core problem of metamaterial applications to the multiple input and multiple output (MIMO) wireless power transfer and harvesting system. An experimental demonstration MIMO-WPTH system will be set up in this project. In order to meet the development trend of wireless mobile terminals and the internet of things, this project will provide innovative solutions to realize the integration of efficient and multi-function wireless power transfer and harvesting system using metamaterials.
