Abstract:

We study the potential of a novel ``quantum metamaterial'' for subwavelength imaging applications in the midinfrared. Because the layers that comprise the metamaterial have in-plane and out-of-plane dielectric responses that are determined by different physical mechanisms (Drude free electron response and quantized electronic transitions, respectively), their resonances are polarization sensitive and can be designed independently. The result is a negatively refracting anisotropic effective medium with losses, described by the figure of meri
