Electromagnetic wave propagation through and reflection from metal nano stripes fabricated with femtosecond laser ablation

Electromagnetic wave propagation through and reflection from grating-like structures is one of the very fundamental and most studied subjects both in electromagnetics and optics. Several theoretical models and numerical solvers have been developed in order to solve this problem as efficiently and accurately as possible for different applications. In this work we experimentally study such phenomenon on metal nano stripe arrays fabricated with femtosecond laser ablation and compare our experimental findings with a full-wave time domain electromagnetic solver.
