Optical Behavior of Elliptical Lenses Made of DNG Metamaterial

The two-dimensional problem of radiation from an isotropic line source located at one of the two focal lines of an elliptic cylinder made of double-negative (DNG) metamaterial is considered in the frequency domain and in the optical limit. The radiated field appears to emanate from a virtual line source located at the other focal line of the DNG elliptical cylinder. Some derivative structures are also examined, leading to a far field whose source appears to be outside the radiating structure.
