Ideal optical antireflection of composite films activated by spherical nanoparticles

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.
