Abstract
An optically-transparent device () is disclosed which comprises a main part () of dielectric material having a refractive index n, 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 nlower than said refractive index n. Said device () further comprises at least one insert () of dielectric material having a refractive index nhigher than said refractive index n, said at least one insert being at least partly inserted into said main part, said refractive index nbeing different from said refractive index n, and wherein Formula (I) with Wbeing a half width of said insert and Formula (II), Formula (III) with Wbeing 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 n.
