Resonant wireless transmission

       Today, I'd like to introduce the resonant wireless transmission mode (2).
       This kind of wireless transmission mode is similar to the principle of wireless communication. The electromagnetic waves of the resonant circuit at the transmitter end diffuse in the whole space in an all-round way, and the resonant circuit at the receiver end resonates at the specific frequency, so as to realize the transmission of energy.
       When the output power of the receiver is small, the transmission efficiency is high. But there is electromagnetic radiation, the larger the transmission power, the farther the distance, the lower the efficiency, the more serious the radiation. Therefore, this method is only suitable for small power and short distance applications.
