FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering and is intended for wireless transmission of electromagnetic energy, for example, in wireless chargers, in information transmission channels, in medical devices. The electromagnetic energy wireless transmission system contains a first resonant circuit with an inductor on the side of the source device and a second resonant circuit with an inductor located on the side of the target device. A metal screen is located between these coils. At the same time, the coupling value of these coils is chosen stronger than the coupling of the resonant circuits with the source device and with the target device so that two pronounced transmission coefficient maxima are observed on the amplitude-frequency characteristic of the direct losses of the resonant circuits, in the case when there is no metal screen. As the operating frequency of the power transmission device, a frequency close to the frequency of the high-frequency maximum of the transmission coefficient is selected.
EFFECT: possibility of transmitting electrical energy through a solid metal housing.
