Phase conjugation and negative refraction using nonlinear active metamaterials.
We present an experimental demonstration of phase conjugation using nonlinear metamaterial elements. Active split-ring resonators loaded with varactor diodes are demonstrated theoretically to act as phase-conjugating or time-reversing discrete elements when parametrically pumped and illuminated with appropriate frequencies. The metamaterial elements were fabricated and shown experimentally to p...
متن کاملNonlinear transmission and spatiotemporal solitons in metamaterials with negative refraction.
We study one- and two-dimensional transmission of electromagnetic waves through a finite slab of a dielectric material with negative refraction. In the case when the dielectric slab possesses an intensitydependent nonlinear response, we observe the nonlinearity-induced wave transmission through an opaque slab accompanied by the generation of spatiotemporal solitons. We solve this problem numeri...
متن کاملOptical anisotropic metamaterials: Negative refraction and focusing
We design 3D metallic nanowire media with different structures and numerically demonstrate they can be effective homogeneous indefinite anisotropic media by showing their dispersion relations are hyperbolic. A nice fitting procedure is exploited to obtain the dispersion relations, from which we retrieve the effective permittivities. The pseudo focusing for the real 3D wire medium agrees very we...
متن کاملNegative index of refraction in optical metamaterials.
A double-periodic array of pairs of parallel gold nanorods is shown to have a negative refractive index in the optical range. Such behavior results from the plasmon resonance in the pairs of nanorods for both the electric and the magnetic components of light. The refractive index is retrieved from direct phase and amplitude measurements for transmission and reflection, which are all in excellen...
متن کاملWater-based metamaterials: Negative refraction of sound.
The index of refraction characterizes the propagation of physical waves through materials. For hundreds of years, the refractive index of physical materials was thought to be an intrinsically positive quantity: as waves move from one medium to the next, they bend but maintain their direction relative to the interface between the two media (Fig. 1a). However, Victor Veselago showed in 1968 that ...
