Advances in Research on Left-Handed Met Materials
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.
