Indefinite materials |
| 摘要 |
A compensating multi layer material includes two compensating layers adjacent to one another. A multi-layer embodiment of the invention produces sub-wavelength near-field focusing, but mitigates the thickness and loss limitations of the isotropic “perfect lens.” An antenna substrate comprises an indefinite material. |
