METHOD FOR ADJUSTING ELECTROMAGNETIC WAVE, AND METAMATERIAL

摘要

The present invention discloses a method for adjusting an electromagnetic wave, and a metamaterial. The 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. According to the present invention, a technical problem that a metamaterial cannot dynamically adjust an electromagnetic wave in a simple and fast manner in the priorart is solved.
