In wireless power transfer systems, the position of a receiver is very important in relation to where the transmitter is. Most resistor-inductor-capacitor circuits may result in a resonant frequency which varies with the coupling coefficient. The coupling coefficient can affect the resonant frequency and cause it to disappear resulting instead in other frequencies at which the received power is a lot less than at resonant. For example, the increase of mutual inductance between two coils leads to splitting in the frequency response of inductive systems. Frequency splitting models have been clearly demonstrated. Many papers show how to obtain frequency splitting for two, three and four coils in near field inductive communication systems. They strongly clarified that in order to transfer wireless power efficiently, the frequency splitting must be avoided. However, none of these papers states that splitting frequency can be very useful if the transmitter sends two signals at the frequencies before induction occurs. In this paper we link frequency splitting to frequency allocation at the transmitter.
