Abstract

See full text

An optically-transparent device (100) is disclosed which comprises a main part (10) of dielectric material having a refractive index n2, said device being configured for forming a field intensity distribution in a near zone of said device from electromagnetic waves incidentally illuminating said device, when said device is embedded into a dielectric material having a refractive index n1 lower than said refractive index n2. Said device (100) further comprises at least one insert (11) of dielectric material having a refractive index n3 higher than said refractive index n2, said at least one insert being at least partly inserted into said main part, said refractive index n1 being different from said refractive index n3, and wherein Formula (I) with W2 being a half width of said insert and Formula (II), Formula (III) with W1 being a half width of said main part and Formula (IV), with λ being the wavelength of the electromagnetic wave propagating in the dielectric material having refractive index n1.
