Doubly Negative Metamaterials

چکیده
In 1967 Veselago considered the possibility of materials with (relative) permittivity and (relative) permeability μ both negative [1]. Building on the long history of artifical dielectrics for high-frequency applications (see, for example, [2, 3, 4]), in 1999 Pendry et al. proposed a technique for fabrication of metamaterials with both negative and negative μ within a certain frequency range [5]. Such materials were first realized in the laboratory in 2000 [6]. An idealized model of the frequency dependence of the permittivity and the permeability (both assumed to be linear and isotropic) is that

Double Negativity in 3D Space Coiling Metamaterials
Metamaterials displaying negative refractive index has remarkable potential to facilitate the manipulation of incident waves for wide variety of applications such as cloaking, superlensing and the like. Space-coiling approach is a recently explored technique to achieve extreme properties. The space coiling phenomena cause less energy absorption as compared to local resonating phenomena for obta...
متن کاملMaterial parameter retrieval procedure for general bi-isotropic metamaterials and its application to optical chiral negative-index metamaterial design.
A chiral optical negative-index metamaterial design of doubly periodic construction for the near-infrared spectrum is presented. The chirality is realized by incorporating sub-wavelength planar silver-aluminasilver resonators and arranging them in a left-handed helical (i.e., stair-step) configuration as a wave propagates through the metamaterial. An effective material parameter retrieval proce...
متن کاملDoubly negative metamaterials in the near infrared and visible regimes based on thin film nanocomposites.
An optical metamaterial characterized simultaneously by negative permittivity and permeability, viz. doubly negative metamaterial (DNM), that comprises deeply subwavelength unit cells is introduced. The DNM can operate in the near infrared and visible spectra and can be manufactured using standard nanofabrication methods with compatible materials. The DNM's unit cell comprise a continuous optic...
متن کاملNear-infrared metamaterials with dual-band negative-index characteristics.
Dual-band negative-index metamaterial designs in the near-infrared frequency range are presented and their performance is analyzed using a full-wave numerical electromagnetic scattering method. Negative effective permittivity is provided by a thin layer of metallic film. Negative effective permeabilities are supplied in two distinct frequency bands by magnetic resonators of different dimensions...
متن کاملStudy of anomalous wave propagation and reflection in semi-infinite elastic metamaterials
Elastic metamaterials have been investigated to achieve negative effective properties, which cannot be found in the conventional elastic medium. In this paper, planewave propagation and reflection in semi-infinite elastic metamaterials with doubly or triply negative material properties are studied analytically and numerically. The unique negative refractions for the longitudinal (P) wave and tr...
