TL;DR: In this paper, the Luneberg lens index profile was used for far-field imaging of (infinitely) distant objects. And they applied the transformation design method to the problem of far field imaging.

TL;DR: In this article, the authors provide an approach for the conversion of evanescent electromagnetic waves to non-evanescent ones by using an artificially-structured material such as a layered structure or other metamaterial.
Abstract: Apparatus, methods, and systems provide conversion of evanescent electromagnetic waves to non-evanescent electromagnetic waves and/or conversion of non-evanescent electromagnetic waves to evanescent electromagnetic waves. In some approaches the conversion includes propagation of electromagnetic waves within an indefinite electromagnetic medium, and the indefinite medium may include an artificially-structured material such as a layered structure or other metamaterial.

TL;DR: As one can see, superlensing appears in a linearelectromagnetic problem and does not need any Btwopaths and Bsynchronization for signal amplification and nonlinearity may limit the resolution.
Abstract: thegiveninitialconditions(e.g.,startofillumination,etc.).The better theQ factor the closer the system may come toan ideal behavior, in the present caseVto superlensing.As one can see, superlensing appears in a linearelectromagnetic problem and does not need any Btwopaths[ and Bsynchronization[ for signal amplification.Nonlinearity may limit the resolution, in addition to otherfactors mentioned above. Since this is a linear problem,thereisnodeteriorationofSNR;bothBsignal[andBnoise[at the source would be restored in the image, i.e., aBblinking[source wouldproduceaBblinking[replica withthe use of an ideal superlens.I hope this answers the questions raised in [1] andclarifies the behavior of theBsuperlenses.[ h
