| 摘要 |
An apparatus includes an object and one or more sensors located adjacent to or in the object. The object is formed of a material whose dielectric constant or magnetic permeability has a negative real part at microwave-frequencies. The one or more sensors are located adjacent to or in the object and measure an intensity of an electric or a magnetic field therein.
