چکیده

Negative refractive index characteristics of a uniaxial anisotropic slab with a negative component of the permeability tensor are first confirmed. A two-dimensional array of metallic spirals is fabricated on a dielectric substrate and the wave propagation guided by the structure is measured by near-field measurements at 4.5 GHz band. The ω-β relation is obtained by the measured phase distributions and the refractive index characteristics are calculated. The measured refractive indices take negative values in accordance with numerical prediction.

Backward Wave Propagation of a Uniaxial Anisotropic -Negative Slab Composed of Metallic Spirals

1. Introduction It has been theoretically shown that backward waves can be supported not only by double-negative materials with simultaneous negative permittivity and permeability [1] but also by uniaxial anisotropic single-negative slabs with a negative component of permittivity or permeability tensor [2]. The uniaxial anisotropic single-negative materials are potentially advantageous in row l...

Q-band tunable negative refractive index metamaterial using Sc-doped BaM hexaferrite

A simple structured tunable negative refractive index (n) metamaterial (TNIM) has been designed, fabricated and tested in a Q-band rectangular waveguide. The structure consists of one slab of single crystalline scandium-doped barium hexaferrite (Sc-BaM), aligned parallel to two rows of periodic copper wires. The magnetic field tunable passband is measured indicating the occurrence of negative n...

Radiative Properties of Multilayer Thin Films with Positive and Negative Refractive Indexes

(i.e., n = − εμ ). A consequence is certain unusual optical features in negative-index media. The electric field vector E, magnetic field vector H and wave vector k are a left-handed triplet, the basis for calling materials with simultaneously negative ε and μ “left-handed materials” (LHMs). LHMs would have novel optical properties. Light at non-normal incidence would bend to the side opposite ...

Investigation tow of negative refraction characters in the three different 2D phononic crystals

In this paper, a two-dimensional phononic crystal comprising of steel rod in water is investigated. Three cross- sections for this rod are considered using finite element method (EFM). We plot the equifrequency surface of the first band, because of equifrequency surface convex around the edge of the first Brillouin Zone, we guess the negative effective phononic mass and so negative refraction. ...
