Composite medium with silver nanoparticles for anti-reflection coating application

Abstract

This research presents a design of simple interference anti-reflection coating consisting of a transparent host and uniformly oriented disc-like silver nanoparticles. This work explores the utility of effective medium representations to simplify the electromagnetic analysis of composite system, and demonstrates the use of this simplification in solving of the boundary problem under consideration. With the help of full-wave finite-element numerical analysis, it is shown that effective-medium approach provides a satisfactory qualitative description of the reflection and transmission spectra in composite layers and confirms their antireflective behavior.
