A study on comparing analytical methods for coil design in high frequency wireless energy transfer

It is commonly accepted that the efficiency of a wireless energy transfer (WET) system depends on the resonance components and mutual inductance of between coils. Before the finite element analysis, applying analytical methods make the design procedure of resonance components faster and reliable. In this paper, some analytic methods are investigated to find values of self-inductance, intra-winding capacitor and mutual inductance between coils. A coil is modeled in the ANSYS MAXWELL and simulated coil is produced to compare the all results.
