Abstract
A metamaterial structure unit, a metamaterial and an electronic device. The metamaterial structure unit includes a first substrate, a second substrate, a liquid crystal layer between the two substrates, and a first electrode on the first substrate and a second electrode on the second substrate. The first electrode includes a first connecting portion, a first strip structure and a plurality of first circular arc structures on a first circumference. The second electrode includes a second connecting portion, a second strip structure and a plurality of second circular arc structures on a second circumference. In a case that the first electrode is rotated by 90 degrees around a center of the first circumference, a projection of the first electrode on the second substrate in a direction perpendicular to the second substrate coincides with the second electrode.
