Simulation of 4-coils Magnetic Resonance Coupling for Multiple Receivers Wireless Power Transfer at Various Transmission Distance

This paper performs a critical review on multiple receivers' wireless power transfer with magnetic resonance with a 4-coils structure. CST software is used for the simulation work to observe magnetic resonance coupling for multiple receiver's wireless power transfer at a varied separation distance between the transmitter coil and receiver coil. Comparative analysis was performed at a separation distance of 3, 6, 9, 12, and 15 cm. Electric and magnetic fields, scattering output and impedance are the output parameters recorded and analyzed.
