Abstract: A positioning method includes transmitting at least two non-diffracting beams to a receive end, where each non-diffracting beam carries corresponding first curve information, and the first curve information indicates a trajectory of the non-diffracting beam; receiving feedback information that corresponds to the at least two non-diffracting beams and that is sent by the receive end, where the feedback information carries second curve information; and determining a first position of the receive end in a first preset coordinate system based on second curve information of the at least two non-diffracting beams.

Abstract: A capacitive sensor, an electronic device, and an electronic device control method are disclosed and relate to the field of sensor technologies. The capacitive sensor includes at least one plate pair. Each plate pair includes a first plate and a second plate that are placed opposite to each other. A ratio of a plate length of each plate pair to a spacing in the plate pair is greater than 1 and less than or equal to 30. The capacitive sensor can detect an air gesture of a user based on fringe field effect and has advantages of a small size and low energy consumption.

Abstract: This application discloses a beam control method and an apparatus. The method includes: obtaining a target propagation track of a beam and a reception point location of the beam, where the target propagation track passes through a transmission point location and the reception point location of the beam; determining target phase information of the beam based on the target propagation track and the reception point location, so that a depth of focus location of the beam overlaps the reception point location; and controlling to transmit the beam based on the target phase information. In embodiments of this application, when the beam is controlled to be propagated to the reception point location along the target propagation track, a focus of the beam also reaches the reception point location along the target propagation track, so that a depth of focus of the beam overlaps the reception point location.

Abstract: An optical waveguide device, an optical chip, and a communication device are provided. The optical waveguide device includes a substrate, a target structure, and an electro-optic crystal structure. The target structure includes an insulation layer and a first optical waveguide. A bonding region of the insulation layer includes a first groove that receives the first optical waveguide, and a surface of the first optical waveguide positioned away from the substrate is flush with a surface of the bonding region that is positioned away from the substrate. The electro-optic crystal structure is bonded to a side of the target structure positioned away from the substrate. This application can resolve a problem that the optical waveguide device has low light modulation efficiency.
