Hazen: Super-Oscillation Papers
- Rogers et al Nature Material, 2012
- replace lens with a diffraction grating pattern. – bright external ring, central spot less than diffraction size (185 nm)
- resolve two slits separated by 140 nm.
- super-oscillations — Functions with only 5 Fourier modes can have tiny features with FWHM much smaller than the smallest Fourier wavelength.
