Wireless Power Transfer Based on Metamaterials
Near-field based wireless power transfer (WPT) technology is promising for many applications from consumer electronics to industrial automation. By utilizing resonant coupling, the power transfer can be made more flexible than conventional inductive WPT. However, the range is still limited. In this chapter, we report research work on near-field wireless power transfer (WPT) based on metamateria...
متن کاملEfficiency Enhancement of Wireless Power Transfer System Using MNZ Metamaterials
In this paper, a simple approach for efficiency enhancement of a wireless power transfer system by using mu near zero (MNZ) type of metamaterial is proposed. A single slab containing onesided periodic structures of 3×3 array of meander-line unit cell has been placed between transmitting and receiving coils in the wireless power transfer system. The presented metamaterial structure is less compl...

متن کاملWireless Power Transfer with Magnetic Conductor Reflectors
In this paper, a wireless power transfer system (WPT) with magnetically coupled resonators is studied. The idea to use a reflector to enhance the coupling coefficient and the transfer efficiency is proposed and analyzed. Perfect magnetic conductor (PMC) was used in numerical calculations in order to study the performance of a reflector. In the WPT system we studied, efficiency is increased from...
