Abstract
Left handed materials, also called metamaterials because they are arti?cial and are not present in Nature, are characterized by having both permittivity and permeability negative.With these properties, metamaterials have a negative refractive index due to which they produce negative refraction making them good candidates to formimages. However, since their early fabrication in the microwave range, losses in meta-materials have been considerable, thus being their refractive and image formation properties highly a?ected by them.
