'Plasmonics' in free space: observation of giant wavevectors, vortices and energy backflow in superoscillatory optical fields
Guang Hui Yuan, Edward T. F. Rogers, Nikolay I. Zheludev
Evanescent light can be localized at the nanoscale by resonant absorption in a plasmonic nanoparticle or taper or by transmission through a nanohole. However, a conventional lens c…

Achromatic super-oscillatory lenses with sub-wavelength focusing
Guang Hui Yuan, Edward T. F. Rogers, Nikolay I. Zheludev
Lenses are crucial to light-enabled technologies. Conventional lenses have been perfected to achieve near-diffraction-limited resolution and minimal chromatic aberrations. However,…
