In this paper an extensive analysis of the magnetic coupling between two resonant coils in air as a means for wireless power transfer is presented. The wireless power transfer system is investigated with reference to capacitance parallel arrangement for emitter and receiver coils. The system is assessed for different system geometries, operating frequencies and load conditions with a computer code implemented in Scilab. The Scilab calculations are validated with finite-element numerical simulations and experimental measurements. The current and voltage gains and efficiency of the system are evaluated with respect to different distances between the two coils.
