An article in Physical Review Letters in 2000 which extended work done by Russian scientist Victor Veselago and suggested a simple method of creating a lens whose focus was theoretically perfect, has become his most cited paper. [9] Initially, it had many critics who could not believe that such a short article could present such a radical idea.
A superlens, or super lens, is a lens which uses metamaterials to go beyond the diffraction limit.The diffraction limit is a feature of conventional lenses and microscopes that limits the fineness of their resolution depending on the illumination wavelength and the numerical aperture (NA) of the objective lens.
Perfect Dark is an upcoming action-adventure first-person shooter video game developed by The Initiative and Crystal Dynamics and published by Xbox Game Studios. Announced at The Game Awards in 2020, it is a reboot of the Perfect Dark series. It is set to be released for Windows and Xbox Series X/S.
The research began with Pendry's proposed "Perfect lens." Several research investigations that followed Pendry's concluded that the "Perfect lens" was possible in theory but impractical. One direction in subwavelength focusing proceeded with the use of negative-index metamaterials, but based on the enhancements for imaging with surface plasmons.

Even a perfect lens will convolve the incoming image with an Airy disk (the diffraction pattern produced by passing a point light source through a circular aperture). [2] Under normal circumstances, these imperfections are not noticeable, but an intensely bright light source will cause the imperfections to become visible.
