ABSTRACT
The exposition of the consequences of light propagation in a material that exhibits both a negative dielectric constant and a negative magnetic permeability was first published by Veselago in 1968 [1]. It set the framework for a number of interesting and unusual properties that derive from this hypothetical condition. Since then a number of articles have appeared dealing with the idea [2,3], we will review his mathematical approach below, as well as how this formalism leads to the interesting physical manifestations. This will be followed by a review of the most recent work that is suggestive of ways to find materials with the desired negative quantities and how well the experiments or simulation conform to what was predicted.
