  Polarization is one of the key properties defining the state of light. It was
discovered in the early 19th century by Brewster, among others, while studying
light reflected from materials at different angles. These studies led to the
first polarizers, based on Brewster's effect. One of the most active trends in
photonics now is devoted to the study of miniaturized, sub-wavelength devices
exhibiting similar, or even improved, functionalities compared to those
achieved with bulk optical elements. In the present work, it is theoretically
predicted that a properly designed all-dielectric metasurface exhibits a
generalized Brewster effect potentially for any angle, wavelength and
polarization of choice. The effect is experimentally demonstrated for an array
of silicon nanodisks at visible wavelengths. The underlying physics of this
effect can be understood in terms of the suppressed scattering at certain
angles that results from the interference between the electric and magnetic
dipole resonances excited in the nanoparticles, predicted by Kerker in early
80s. This reveals deep connection of Kerker's and Brewster's legacies and opens
doors for Brewster phenomenon to new applications in photonics, which are not
bonded to a specific polarization or angle of incidence.
