The invention relates to a method for synthesizing a vortex electromagnetic field with a high orbital angular momentum mode number. The method for synthesizing the vortex electromagnetic field comprises the following steps: N antenna units form a circular antenna array, and by rotating the circular antenna array and regulating and controlling the phase of each antenna unit, the vortex electromagnetic field is synthesized, wherein N is an integer larger than or equal to 1. By utilizing the method provided by the invention, the synthesized vortex electromagnetic field with the target mode numbercan be generated as required, and the vortex electromagnetic field with the high mode number is directly synthesized by rotating the antenna array and regulating and controlling the phase of each antenna unit under the condition of a small number of antennas, so that the resolution of the imaging system in the azimuth direction is increased. The vortex electromagnetic field synthesized by using the method disclosed by the invention not only is beneficial to realizing super-resolution imaging, but also has remarkably improved modal purity, and has a very good application prospect in the fieldsof super-resolution biomedical imaging, radar imaging, wireless communication and the like.

An unmanned aerial vehicle delivery system based on smart windows, including a user terminal, a smart window, a drone, and an express operation control terminal. The window at least includes a sensing module 1 and a driving mechanism. The drone is equipped with a sensing module 2.

To provide an electric actuator that can be maintained without discharging all the power stored in the storage body, without forgetting the operation of returning to the normal use state, and without time constraints. A switch (up and down slide switch) (31) is provided on the passage for supplying electric power from the storage body (30) to the motor (25). A bar member (42) having protrusions (42a), (42b), (42c), and a button (42d) is provided. In the state where the operating end is fully closed and the power supply from the accumulator (30) to the motor (25) is cut off, press the button (42d) to press the gear (35) so that the motor (25) and the output Axis (37) is not connected. Again, the control lever (31a) is pressed up with the protrusion (42b) to make the switch (31) closed. When the power-on state switching switch (31) of the closed state is re-energized, the protrusion (38a) of the cam (38) presses the control lever (31a) by the rotation of the output shaft (37), and automatically returns to the off state. open state.
