Abstract
A beam reconstruction method includes: generating or receiving a radio frequency signal, determining a to-be-adjusted beam angle, loading a voltage bias value on each liquid crystal metasurface array unit among a plurality of liquid crystal metasurface array units in a liquid crystal metasurface array based on the beam angle, and either emitting the generated radio frequency signal transmitted through the liquid crystal metasurface array or directing the received radio frequency signal through the liquid crystal metasurface array to a feed of an antenna. A lateral offset of a feed phase center is generated based on the voltage bias value after the radio frequency signal is transmitted through the liquid crystal metasurface array.
