Transmission efficiency η and power of the load P L as a function of spacing distance. Transmission efficiency η and power of the load P L as a function of spacing distance is shown in this figure. The transmission efficiency η curves of theoretical value and experimental value when the frequency can be varied decay with the increase of distance. When the frequency is constant, there is a peak value of the load P L . The curve shows that the error between theoretical calculation and actual measurement is relatively small
