Abstract
A metamaterial comprises a plurality of electrically controllable metamaterial units each comprising a varactor diode; the predetermined angle is an angle at which an electromagnetic wave is reflected from a surface of the metamaterial; there is an association relationship between the predetermined angle and the first phase difference; the method comprises: determining a first phase difference between electromagnetic waves reflected by two adjacent electrically controllable metamaterial units in a metamaterial based on a predetermined angle; determining a target capacitance of the varactor diode in each electrically controllable metamaterial unit based on the first phase difference; and adjusting a capacitance of the varactor diode in each electrically controllable metamaterial unit to the target capacitance.
