latex combined interlayer, working on resonant coupling between two coils is proposed to realize efficient wireless energy transfer. A fabricated analytical model for the system has been designed for the study of electrical energy delivery. Related figures have been presented to showcase its performance. Then the experiments have been carried out and the output voltages, the output power, and the efficiency at the receive side with different distance have been measured for verification. The results show that the natural frequency becomes much lower for the proposed novel charger, and yet at the same time, operates with good performances. The analysis reported allows a formal design procedure to be established for the optimization of Witricity transfer for a given application.
