Left-handed metamaterials, of which the dielectric constant and the magnetic permeability are sim-ultaneously negative, are a kind of electromagnetism materials. This paper gives a introduction to the basic principles of left-handed materials, and expatiates on the preparation ways of this materials in microwave region,infrared region and visible light region.
