Artificial microstructure and metamaterial using the same

A metamaterial, comprising:

• at least one metamaterial layer, and each metamaterial layer comprising:
• a substrate;
• and
• at least one artificial microstructure attached to the substrate, and each artificial microstructure comprising:
• a first metal wire;
• a second metal wire parallel to the first metal wire;
• at least one first metal wire branch;
• and
• at least one second metal wire branch, wherein the at least one first metal wire branch and the at least one second metal wire branch are distributed in an interlacement arrangement, one end of the at least one first metal wire branch is connected to the first metal wire, the other end is defined as a free end facing towards the second metal wire;
• one end of the at least one second metal wire branch is connected to the second metal wire, and the other end of the at least one second metal wire as a free end faces towards the first metal wire.
