By using a network approach, a wireless inductive link for power transmission from multiple transmitters to multiple receivers is considered. The problem of maximizing the power delivered to the receivers is solved and analytical formulas are presented and validated by circuital simulations.
A prerequisite for efficient realization of wireless power transfer (WPT) links is that the power is transmitted to the receivers without reflections. Satisfaction of this condition requires the load impedances to be equal to the conjugate image impedances at respective ports of the system. According to the knowledge of the authors, determination of the conjugate image impedances has been feasible...
