Abstract	Wireless power transfer via magnetic resonant coupling has been extensively researched for various applications. Impedance matching is implemented so that the transfer system is resilient to positional changed and load changed. Recently powering multiple loads simultaneously is becoming the focus in wireless power transfer researches and designs. Apart from maintaining high efficiency, controllable power division is also an important feature in multi-receiver system. This is due to ratio of power division depends not only on the load but also on the gap of each receiver to the transmitter. On the other hand, cross coupling exists when receivers are placed relatively near to each other. In this paper, novel algorithm is proposed for impedance matching and power division considering cross coupling in between two receivers. The wireless power transfer system is first represented by equivalent circuit and the algorithm for impedance matching and power division is derived. The new method is then verified using simulations.
