It is shown that the resolution of virtual images of dye-doped dielectric nanospheres obtained through dielectric microspheres can be increased beyond the classical diffr[...]

Superoscillation is a physical phenomenon, in which the local oscillations of a bandlimited signal fluctuate faster than the fastest Fourier component of the signal. In r[...]

Dielectric microspheres with diameters (D) on the order of several wavelengths of light have attracted increasing attention from the photonics community due to their abil[...]

Optical microscopy is one of the oldest and most important imaging techniques; however, its far-field resolution is diffraction-limited. In this dissertation, we proposed[...]
