چکیده
Microwave waveguide measurements of negative index media (NIM) are reported. Accurate determination of the frequency variation of the complex scattering parameters yields the refractive index " ' ) ( ~ in n n + = ω for the NIM with ' n varying between -3.9 to -0.3 in the passband region of 9.7-10.5 GHz. The results show that transmission is optimized for 1 ' − ≈ n and small " n . PACS numbers: 78.20.Ci, 42.25.Bs, 41.20.Jb, 42.70.Qs

A New Compact Double-Negative Miniaturized Metamaterial for Wideband Operation
The aim of this paper is to introduce a compact double-negative (DNG) metamaterial that exhibits a negative refractive index (NRI) bandwidth of more than 3.6 GHz considering the frequency from 2 to 14 GHz. In this framework, two arms of the designed unit cell are split in a way that forms a Modified-Z-shape structure of the FR-4 substrate material. The finite integration technique (FIT)-based C...
متن کامل5 Negative Refraction in Photonic Crystals
The phenomenon of negative refraction (NR) by 2D photonic crystals (PCs) is demonstrated in microwave experiments. NR by PCs is observed in 2D parallel-plate waveguide and in 3D free space measurements. Results are in excellent agreement with band structure calculation and numerical simulation. The optical properties of isotropic materials that are transparent to electromagnetic (EM) waves can ...

Microwave nondestructive testing methods become nowadays ever more exploited electromagnetic evaluation method not only dielectric but also metal materials surface and volume homogeneity. A novel microwave sensor created from open waveguide with metamaterial structure for non-destructive testing was developed in an attempt to increase the sensitivity of the microwave nondestructive evaluation m...
متن کاملWaveguide devices with homogeneous complementary media.
We report the design of microwave waveguide devices based on complementary media. Various kinds of waveguide devices that possess nearly 100% transmission efficiency are proposed, such as waveguide bends, splitters, connectors, and shifters. Compared with previous work on waveguide devices of low reflection and minimized distortion based on transformation optics, our transform media are homogen...
متن کاملCharacteristics of bound modes in coupled dielectric waveguides containing negative index media.
We investigate the characteristics of guided wave modes in planar coupled waveguides. In particular, we calculate the dispersion relations for TM modes in which one or both of the guiding layers consists of negative index media (NIM)-where the permittivity and permeability are both negative. We fi nd that the Poynting vector within the NIM waveguide axis can change sign and magnitude, a feature...
