“…In addition, the metamaterial in the WPT system with different positions has been proposed. Many works have studied the position of the 3D metamaterial for enhancing the performance of the WPT system, including middle [37,45], front [38], and back [47] of 2D slab [44,45,127] 3D slab [37][38][39][40][41][42][43], [45,47,128] the WPT system. It should be noted that more researches are focus on the different number of 1D metamaterial because of the bulky volume of the 3D metamaterial.…”

“…The unit cell of the metamaterial is the split ring resonators (SRR) loaded with capacitors, which is fabricated on the Taconic's CER-10 dielectric slab with a length of 12 cm [38]. In [42] and [43], the Kyung Hee University proposed a metamaterial of three-turn spiral resonators (3T-SR) with size of 15 cm. The 3T-SR is embedded on the acrylic board and the material is made up of the metal copper sheet with a thickness of 0.2mm.…”

As a unique group of advanced artificial materials, metamaterials have found many interesting applications in various devices due to the ability to control electromagnetic fields. The metamaterial provides the prospect of new opportunities for the wireless power transfer (WPT) system to improve efficiency and reduce magnetic flux density. This review paper evaluates the performance of the WPT system with metamaterial from both principles and functions aspects. The objectives of this review include: (1) to present the research process and bottlenecks of metamaterial in the WPT system; (2) to clarify the design solution and checking method of the metamaterial and (3) to identify the challenges and opportunities based on the functional of the WPT system integration with metamaterial. Therefore, the process on metamaterial design, working principle of metamaterial, optimal method, equivalent model, and experimental method are reviewed. The recent efforts of the WPT system with metamaterial in efficiency enhancement, misalignments, magnetic field reduction are illustrated. Finally, the challenges and prospects of metamaterial based on the WPT system are concluded.

Wireless power transfer (WPT) is a technology that enables energy transmission without physical contact, utilizing magnetic and electric fields as soft media. While WPT has numerous applications, the increasing power transfer distance often results in a decrease in transmission efficiency, as well as the urgent need for addressing safety concerns. Metamaterials offer a promising way for improving efficiency and reducing the flux density in WPT systems. This paper provides an overview of the current status and technical challenges of metamaterial-based WPT systems. The basic principles of magnetic coupling resonant wireless power transfer (MCR-WPT) are presented, followed by a detailed description of the metamaterial design theory and its application in WPT. The paper then reviews the metamaterial-based wireless energy transmission system from three perspectives: transmission efficiency, misalignment tolerance, and electromagnetic shielding. Finally, the paper summarizes the development trends and technical challenges of metamaterial-based WPT systems.
