Abstract: Our aim is to introduce the partial coherence theory in metamaterials research. We will be dealing with the partially coherent light beam interaction with negative refractive index materials. As is well known negative index metamaterials is a relatively new topic. And interaction of metamaterials is limited to Gaussian light beams. Therefore, it is necessary to consider all type light beams having different coherence values. We will here show the statistical results of Gaussian Schell-model light beam passing through negative refractive index and positive refractive index material layer. And we will discuss possible further improvements via different types of random light beams. The metamaterial layer we use is also known as perfect lens. It consists of a negative refractive index material stacked into two positive refractive index materials. Our formulation is based on the ABCD-matrix approach and generalized Huygens-Fresnel principle. Therefore, numerical calculations can be shrinked into Gaussian beams. In the analysis, we’ve found that perfect lens like configuration causes blue/red shifts in the spectrum which is because of the boundary between layers. In conclusion, these types of research are extremely important because these devices are used to manipulate electromagnetic radiation.
