Wireless power transfer of magnetic resonances

The contactless feed system of the electric power is studied and put to practical use. Many of these systems are based on the principle of electromagnetic induction. Therefore, there is a challenge to meet both transmission efficiency and transmission distance requirements. Recently, the method "magnetic resonance" was proposed at MIT and was verified with a prototype. This highly effective method can achieve high power and long-distance transmission. To realize a practical design, knowledge of electric circuit logic and electromagnetic theory are required.
