Potentialities of PMMA composite films with silver nanoclusters as highly effective nanostructural optical antireflection coatings of silicon solar cells are investigated in a wavelength range from...

It has been shown that a composite film activated by spherical nanoparticles can ensure ideal optical antireflection when the amplitude of the transmitted light wave is equal to the amplitude of the external wave at various angles of incidence independently on the optical properties of the underlying medium. The amplitude of the reflected wave vanishes in a wide range of optical wavelengths. It has been shown that the effect of ideal optical antireflection occurs when the effective complex refractive index of the composite film is zero.

It has been shown that the intensity of the electric dipole radiation from an atomic cluster with a certain arrangement of atoms can be much larger (by a factor of 10³–10⁸) than the radiation intensity from an isolated atom owing to the interatomic interaction. This giant enhancement of light is accompanied by a significant change in the radiation spectrum.

This paper solves the problem of the interaction, via the field of virtual photon field with the emission or absorption of a real photon, of two atomic electrons located at arbitrary distances from...
