The invention discloses a double-focusing field electromagnetic tweezer implementation method based on a time reversal spatial and temporal focusing mechanism, and belongs to the technical field of electromagnetic wave non-contact operation and control. According to the implementation method, a TR electromagnetic wave spatial and temporal focusing transmission mechanism is used as foundation, and two parallel focusing spots are generated through a planar time reversal mirror; and a hollow region with extremely weak electromagnetic field strength generated by an electromagnetic interference cancellation mechanism is generated between the two focusing spots to form an electromagnetic field gradient trap to generate required thrust and gradient force, so as to catch or control tiny particles with electric neutrality or weak current. Compared with a single-spot electromagnetic wave focusing field, the double-focusing field can remarkably lower scattering force, improve the gradient force of the electromagnetic field trap, and overcome the shortcomings of relatively weak dynamic action of the electromagnetic wave at frequency band of less than optical frequency band; in addition, the trap depth of the electromagnetic field can be increased, and the stability of the electromagnetic field at frequency band of less than optical frequency band in catching and controlling particles can be improved; and in addition, a large amount of particles with electric neutrality or weak current can be constrained in the narrow and long hollow region at the same time.
