Abstract

Wireless power charging includes interesting physics from low frequencies and RF analysis which tends to be complex and tedious to model and simulate. Full wave simulations has been performed in order to evaluate the wireless power efficiency. A square coil was used to perform this analysis and simulations shows pick values of efficiency of 70% around 5 MHz, which is higher than most found at this frequency. The method has been proved, it is simple to implement in a commercial electromagnetic simulator. Then, it can easily be replicated and optimized to find optimal geometries of coil for specific applications such mobile phones, wearable devices or even electric car charging.
