Abstract:
     The disclosed material is composed of single insulation type ferromagnetic material in negative magnetic permeability or insulation type ferrous magnetic material and metal conductor wire. The said metal conductor wire is embedded into the said single insulation type ferromagnetic material or insulation type ferrous magnetic material evenly. Based on array of metal wire, the invention supplies three kinds of materials in negative refractive index: 1D lattice, 2D lattice, and 3D lattice. Media in negative index are produced by superposing single insulation type ferromagnetic material in negative magnetic permeability or insulation type ferrous magnetic material in broadband with array structure of metal wire in broadband single negative dielectric constant. Features are: wide working frequency, changeable refractive index by applied adjust and control magnetic field, simple preparation method and using mature technologies.
