Asymmetric Reflectance and Cluster Size Effects in Silver Percolation Films

TL;DR

This paper presents a scaling-theory based model that explains the giant asymmetry in reflectance and other optical anomalies in silver percolation films near the percolation threshold.

Contribution

It introduces a quantitative description and a novel scaling-theory approach to understand optical properties of semicontinuous metal films.

Findings

Reproduces spectral properties of semicontinuous composites

Explains origin of loss, reflectance, and transmittance anomalies

Provides insight into percolation threshold effects

Abstract

We develop a quantitative description of giant asymmetry in reflectance, recently observed in semicontinuous metal films. The developed scaling-theory based technique reproduces the spectral properties of semicontinuous composites, as well as provides insight into the origin of experimentally observed loss, reflectance, and transmittance anomalies in the vicinity of the percolation threshold.
