Abstract:
The possibility of antireflection of nonabsorbing dielectric surface with the help of heterogeneous composite with silver nanoparticles of nonspherical forms is shown. The presented results of theoretical investigation correspond to the case when silver nanoparticles are embedded at sub-wavelength depth in the antireflected medium.

Key words:
metal-dielectric composite, silver nanoparticles, plasmon resonance, antireflection coatings.
