“…Panina et al [76] have proposed the use of pairs of parallel metal sticks (with lengths ∼100 nm) periodically embedded in a dielectric medium as an effective medium with negative magnetism at infrared frequencies. Hsu et al [64] have claimed resonance with the original SRR at a wavelength of 10.6 µm. But the size of the SSR was 10.48 µm and the assumption of an effective medium would hardly be valid.…”

In the past few years, new developments in structured electromagnetic materials have given rise to negative refractive index materials which have both negative dielectric permittivity and negative magnetic permeability in some frequency ranges. The idea of a negative refractive index opens up new conceptual frontiers in photonics. One much-debated example is the concept of a perfect lens that enables imaging with sub-wavelength image resolution.Here we review the fundamental concepts and ideas of negative refractive index materials.First we present the ideas of structured materials or meta-materials that enable the design of new materials with a negative dielectric permittivity, negative magnetic permeability and negative refractive index. We discuss how a variety of resonance phenomena can be utilized to obtain these materials in various frequency ranges over the electromagnetic spectrum. The choice of the wave-vector in negative refractive index materials and the issues of dispersion, causality and energy transport are analysed. Various issues of wave propagation including nonlinear effects and surface modes in negative refractive materials (NRMs) are discussed. In the latter part of the review, we discuss the concept of a perfect lens consisting of a slab of a NRM. This perfect lens can image the far-field radiative components as well as the nearfield evanescent components, and is not subject to the traditional diffraction limit. Different aspects of this lens such as the surface modes acting as the mechanism for the imaging of the evanescent waves, the limitations imposed by dissipation and dispersion in the negative refractive media, the generalization of this lens to optically complementary media and the possibility of magnification of the near-field images are discussed. Recent experimental developments verifying these ideas are briefly covered.

“…This has become well known subsequently as the split ring resonator-SRR for short. The SRRs are the basis of most of the meta-materials exhibiting negative magnetic permeability today [4,5,[25][26][27][62][63][64].…”

“…As far as we know, this SRR array is the first negative µ material. Recently, experimental studies of magnetic properties of SRRs have been reported in the THz region [8], particularly at 30 THz (10 µm wavelength) [9], and 100 THz (3 µm wavelength) [10]. On the other hand, theoretical studies of SRR behavior have been done from THz to near-infrared region [11,12].…”

Abstract-Bandpass filter design using metallic split ring resonators (SRR) at optical frequencies is theoretically investigated in this paper. The transmission and reflection coefficients and the transmission phase of SRR array will be analyzed. We will show that there are many magnitude peaks in transmission coefficient that can be used as bandpass filter in 1550 nm-band. Increasing the number of SRR layers will cause increase in the number of magnitude peaks and narrowing of the bandwidth. The numerical analysis is performed using the transfer matrix method (TMM).

“…Metamaterial-style structures with negative index of refraction ͑n = ͱ ͱ ͒ were initially constructed and tested at microwave frequencies. 3,4 They have since advanced through infrared, 5,6 and are now at a stage where direct applications are within reach. To date, these structures have largely been of the "wine-crate" construction, 7 which is an array of split-ring resonators ͑SRRs͒ and wires.…”

Articles you may be interested inA three-dimensional self-supporting low loss microwave lens with a negative refractive index Metamaterial structures designed to have simultaneously negative permittivity and permeability are known as left-handed materials. Their complexity and our understanding of their properties have advanced rapidly to the point where direct applications are now viable. We present a radial gradient-index lens with an index of refraction ranging from −2.67 ͑edge͒ to −0.97 ͑center͒. Experimentally, we find that the lens can produce field intensities at the focus that are greater than that of the incident plane wave. These results are obtained at 10.3 GHz and in excellent agreement with full-wave simulations. We also demonstrate an advanced fabrication technique using conventional printed circuit board technology which offers significant design, mechanical, and cost advantages over other microwave lens constructions.
