Abstract and Keywords
This article focuses on left-handed metamaterials (LHMs). It begins with a discussion of negative-permeability metamaterials, with particular emphasis on split-ring resonators (SRRs) and SRRr arrays and how magnetic permeability influences the response of materials to the incident magnetic field. It then considers the transmission spectra of SRR, LHM and a composite metamaterial as well as the reflection characteristics of a one-dimensional double-negative material. It also examines the effect of disorder on the transmission and reflection properties of ordered left-handed materials, along with the negative refraction, negative phase velocity, and subwavelength imaging and resolution of LHMs. The article concludes with an analysis of planar negative-index metamaterials.
Keywords: left-handed metamaterials, negative-permeability metamaterials, split-ring resonators, transmission, reflection, disorder, negative refraction, negative phase velocity, subwavelength imaging, negative-index metamaterials
