21 Dec 2004 | | Journal: | New J. Phys. 7, 220 (2005) DOI: 10.1088/1367-2630/7/1/220 | | Subject: | Optics; Materials Science | physics.optics cond-mat.mtrl-sci | | Abstract: | We describe the properties of birefringent left-handed metamaterials and introduce the concept of a birefringent perfect lens. We demonstrate that, in a sharp contrast to the conventional left-handed perfect lens at $epsilon=mu=-1$, where $epsilon$ is the dielectric constant and $mu$ is the magnetic permeability, the birefringent left-handed lens can focus either TE or TM polarized waves or both of them, allowing a spatial separation of the TE and TM images. We discuss several applications of the birefringent left-handed lenses such as the beam splitting and near-field diagnostics at the sub-wavelength scale. | | Source: | arXiv, physics/0412128 | | Services: | Forum | Review | PDF | Favorites | |
