ABSTRACT
Left-handed metamaterials (LHMs) have become a remarkable research area and have received a considerable amount of interest due to their exotic electromagnetic properties that are not attainable from common materials. The left-handed media phenomenon was brought to the attention of the scientific community by Veselago four decades ago and has received great attention in recent years since the first experimental demonstration of LHMs by Smith et al. The response of materials to the incident magnetic field is determined by magnetic permeability. The absence of the negative values of magnetic permeability provided little motivation for studying negative-index materials. A perfect lens is one of the most important applications of materials with a negative refractive index. The term, perfect lens, was coined by Pendry owing to the ability of such lenses to reconstruct a perfect image by recovering the evanescent components of Electomagnetic waves.
