How researchers see this paper

The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Optical super-oscillations: sub-wavelength light focusing and super-resolution imaging (2013, methodology): “Conceptually, this is similar to works on super-focusing with pupil filters, as first discussed by Di Francia [17], and developed in, for example, [53, 55, 57] and reviewed in [4].”
Microscopy and its focal switch (2008, background): “Of course, ideas were put forward that claimed to allow for 'far-field' super resolution, such as the Toraldo pupil filter”
An insight into optical metrology in manufacturing (2020, unknown): “Aiming to improve the lateral resolution of optical imaging, in 1952, di Francia introduced a method of employing a pupil filter in an optical imaging system [346].”
Roadmap on superoscillations (2019, background): “We shall note that in a very different context Di Francia also theoretically proposed using a phase mask in the pupil plane of a lens to achieve small hot-spots [44].”
