Abstract

The invention discloses a wireless common-source wireless energy transmission method and system. The system consists of a wireless common source device, N TR energy transmission devices, and M users,wherein M and N are positive integers. The method comprises the following steps: the wireless common-source device radiates a single-frequency common-source signal to the surrounding space through a transmitting antenna of the wireless common-source device; The N TR energy transmission devices receive the common source signals through their own receiving antennas, and generate N TR energy transmission signals with specific amplitudes and phases through phase shifting and amplification operations. The N TR energy transmission devices simultaneously radiate the N TR energy transmission signals through their own transmitting antennas to generate a required single-point or multi-point focusing field to charge one or more of the M subscribers. The N TR energy transmission devices simultaneouslyradiate the N TR energy transmission signals through their own transmitting antennas to generate a single-point or multi-point focusing field to charge one or more of the M subscribers. The N TR energy transmission devices have no source, share the same radio source, and can maintain stable phase difference between each other. Therefore, the technical scheme of the invention can be used for solving the wireless synchronization problem between a plurality of spatially separated time inversion TR transmitting array elements.

Description

technical field [0001] The invention relates to the technical field of wireless energy transmission, in particular to a wireless common source wireless energy transmission method and system. Background technique [0002] Time Reversal (TR, Time Reversal) is a new type of acoustic wave transmission and control technology developed at the end of the 20th century. It was introduced into the field of electromagnetics by M. Fink and his research group members in 2004. The central idea of ​​TR is to propagate sound or electromagnetic waves back to the original source in a complex environment. Theoretical and experimental studies have shown that TR electromagnetic waves can simultaneously form a point focus at one or more designated target positions. Under certain conditions, they can also It exhibits sub-wavelength focusing characteristics beyond the Rayleigh diffraction limit and produces high-precision non-diffraction electromagnetic beams. These unique physical properties allo...
