Abstract:
1. An artificial electromagnetic material comprising: at least one material sheet, each material sheet comprising a substrate and a plurality of artificial microstructures attached to the substrate, each substrate being virtually divided into multiple of substrate units arranged in an array, a pair of artificial microstructures being attached to each substrate unit, the pair of artificial microstructures comprising a first artificial microstructure and a second artificial microstructure having different shapes, wherein the first artificial microstructure comprises an I-shape structure and two split ring structures, the I-shape structure comprises two parallel sides and an intermediate connecting line connected to the parallel sides, two terminals of each split ring structure face toward each other to form an opening, and two openings of the two split ring structures face each other, the two split ring structures are connected with the intermediate connecting line of the I-shape structure, and the intermediate connecting line crosses through the two split ring structure until the parallel sides; the second artificial microstructure comprising two mutually orthogonal I-shaped structures, each end of the two parallel sides of the I-shaped structure connected with a wire segment extending towards the space composed of the edge of the two I-shaped structures and the second artificial microstructure comprises four branches with a same intersection point, one end of any one of the branches connected to the intersection point and the other end is defined as a free end.
