Circuit Model for Fast Computational Analysis of RWPT Applications

Résumé

This work proposes a circuit model to calculate the current along printed coils used in resonant wireless power transmission systems. The proposed formulation is based on the Neumann formula for calculating the mutual inductance between coils, and due to the generality of this approach, it can be applied to more complex structures such as metasurfaces. Finally, this formulation is used to calculate the scattering parameters of the entire system, making it possible to evaluate its wireless power transfer efficiency. The results obtained agree with the general behavior obtained from electromagnetic simulations in commercial software, with a low error and a reduction in computational time of almost three orders of magnitude.
