| Abstract: | 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. |
