A positive future for double-negative metamaterials

Abstract

Metamaterials (MTMs), which are formed by embedding inclusions and material components in host media to achieve composite media that may be engineered to have qualitatively new physically realizable response functions that do not occur or may not be easily available in nature, have raised a great deal of interest in recent years. In this paper, we highlight a large variety of the physical effects associated with double-and single-negative MTMs and some of their very interesting potential applications. The potential ability to engineer materials with desired electric and magnetic properties to achieve unusual physical effects offers a great deal of excitement and promise to the scientific and engineering community. While some of the applications we will discuss have already come to fruition, there are many more yet to be explored. This material is posted here with permission of the IEEE.

Multiband and Miniaturized dual layer Antenna incorporated with FSS and DGS

“…The microstrip antennas are enriched by revolution in electronic circuitry, which lead to miniaturization and integration of antenna in wireless communication devices. Techniques of miniaturization, bandwidth and gain enhancement of microstrip Patch Antenna is an active area for current research topics as on today requirement for compact designs is increasing vastly [2][3][4][5][6]. Frequency selective surfaces and Metamaterials are periodic conductive surfaces, which are artificially made to increase the performance of Antenna for communication system.…”

Application of Double Zero Metamaterials as Radar Absorbing Materials for the Reduction of Radar Cross Section

“…We intend to introduce a class of materials called double zero (DZR) metamaterials [1][2][3][4][5][6][7][8][9], of which the permittivity and permeability are purely imaginary [namely Re(ε r ) = 0 & Re(µ r ) = 0]. Similarly, we may consider epsilon zero (EZR) metamaterials, of which the permittivity is purely imaginary [namely Re(ε r ) = 0 & Re(µ r ) = 0] and mu zero (MZR) metamaterials, of which the permeability is purely imaginary [namely Re(ε r ) = 0 & Re(µ r ) = 0].…”

A General Framework for the Analysis of Metamaterial Transmission Lines

“…Such a topic has recently received a renewed interest as a consequence that experimental evidence of left-handed (LH) materials properties has been given by Smith et al [3,4] who demonstrated an LH structure made of negative-ε thin-wires and negative-µ split-ring resonators exhibiting anomalous refraction at the boundary. Since then many different applications of metamaterials have been developed [5][6][7]. Among the others, artificial transmission lines have been presented which can mimic the propagation characteristics of TEM-based transmission systems filled with homogeneous, linear and isotropic negative refraction index bulk media.…”
