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[...]

A mature and difficult problem, still preoccupying many research communities in different application areas, is the recovery of a quantitative image of some unknown penet[...]

The problem of reconstructing an image of the permittivity distribution inside a penetrable and strongly scattering object from a finite number of noisy scattered field m[...]
