Mechanisms of perfect absorption in nano-composite systems

Olivier Martin, Sebastian Mader

Near-perfect absorption across the entire VIS based on metallic nano-composite materials was realized experimentally by Hedayati et.al. in 2011 and optimized based on simulations by Etrich et.al. in 2014. However, both works did not reveal the mechanisms t ...
