Figure 1. Microscopic interpretation of Brewster effect and proposed metasurface.

(a) p-polarized light impinging on a dielectric medium, ɛ≠1 and μ=1, under usual Brewster's condition. Red line shows 2D emission diagram of electric dipoles excited inside the material by the refracted wave. (b) Same as in a but for s-polarized incidence, for which no Brewster effect can be observed. (c) Generalized Brewster effect for a dielectric medium with electric and magnetic response, ɛ≠1 and μ≠1. Blue line shows 2D emission diagram of interfering electric and magnetic dipoles excited inside the material by the refracted wave. (d) Generalized Brewster effect in the proposed array of high refractive index nanoparticles.
