The Future of Satellite Communication Antennas: Negative Refractive Index Metamaterials - A Review

Free registration required

Executive Summary

Now-a-days, electromagnetic meta-materials is a rapidly growing research domain involving electromagnetism, microwave and milli-metre wave technology, optics, material technology and nanotechnology. In particular, paper concerns about the utilization of split ring resonators in negative permeability meta materials, the concept and the production of an isotropic negative permeability medium, an isotropic negative permittivity medium, CPW supporting propagation of a left-handed wave, and wire media exhibiting negative permittivity. The first attempt to explore the concept of artificial materials appears to trace back to the late part of the nineteenth century when in 1898 Jagadis C Bose conducted the first microwave experiment on twisted structures - geometries that were essentially artificial chiral elements by today's terminology.
