Abstract
An electromagnetic wave control apparatus includes an upper electrode layer, a lower electrode layer, a liquid crystal layer, and a first metamaterial layer disposed between the upper electrode layer and the lower electrode layer. The first metamaterial layer includes a first array including alignment unit structures. A first surface of the alignment unit structure is a surface that is of the alignment unit structure and that faces away from the liquid crystal layer. A length-to-width ratio of the first surface of the alignment unit structure is greater than 1. A length of the first surface, a width of the first surface, and a spacing between two adjacent alignment unit structures range from 1 nm to 5000 nm.
