“…Clearly, if the particle is surrounded not by vacuum but by the medium with dielectric permittivityε m , the permittivity ε in (5) is relative rather than absolute, and k 0 must be replaced by k = k 0 √ε m . Let us use the principle of parallel translational symmetry [37,38], according to which an electric field (an external wave or the wave reflected from the substrate surface) incident on a layer of nanoparticles meets the condition…”

Abstract-This work examines reflection of a light from a semiinfinite medium which is modified with an ordered monolayer of spherical nanoparticles placed on or under its surface. We derive analytical expressions for the electric fields within and outside such structures and verify them with help of strict numerical simulations. We show that nanoparticles layer acts as an imaginary zero-thickness surface having complicated non-Fresnel reflection coefficients with wavelength dependent phase shift. It is shown that such monolayers may reduce reflection relative to reflection from a pure substrate surface. We derive and analyse a zero-reflection condition in the simple intuitive form. It is shown that a single layer of nanocavities near the medium-vacuum interface may increase the transparency of a dielectric medium to values close to 100% in a wide wavelength range.

The boundary problem of linear classical optics about the interaction of electromagnetic radiation with a thin dielectric film has been solved under explicit consideration of its discrete structure. The main attention has been paid to the investigation of the near-zone optical response of dielectrics. The laws of reflection and refraction for discrete structures in the case of a regular atomic distribution are studied and the structure of evanescent harmonics induced by an external plane wave near the surface is investigated in details. It is shown by means of analytical and numerical calculations that due to the existence of the evanescent harmonics the laws of reflection and refraction at the distances from the surface less than two interatomic distances are principally different from the Fresnel laws. From the practical point of view the results of this work might be useful for the near-field optical microscopy of ultrahigh resolution.

The Local Field and What It Means

The easy link between the dielectric constant of isotropic media and the molecular polarizability of the constituents, is traditionally given by the Lorentz-Lorenz (LL) relation. The local field concept however upon which this relation is based, needs to be re-examined for highly inhomogeneous systems, like surfaces and interfaces. Local fields belong inherently to discrete dipole models, but for the comparison with continuum approaches only descriptions based on average fields, are the more suited ones. This holds particularly for the comparison with the Fourier-type solution of the continuum problem, upon which the classical Adler and Wiser papers [1, 2] are based.
