A critical review on wireless power transfer systems using metamaterials

Recently, wireless power transfer (WPT) has been a topic of interest due to its attractive applications in modern life. Starting from Tesla’s idea about century ago, WPT developed tremendously and appeared many the most electronic devices. However, some systems still have limitations such as short transmission distance, low efficiency, electromagnetic leakage. Magnetic metamaterial (MM) is potential candidate that can overcome above disadvantages WPT. This paper intended present an overview recent advances research progress on systems. Three classes consisting short-range, mid-range, long-range, will be analyzed detail both terms fundamentals applications. Especially, MM configurations used enhance near-field efficiency reduce leakage field also evaluated. article expected provide comprehensive review mechanism well future development metamaterial-based
