A fast Fourier transform implementation of the Kramers-Kronig relations: Application to anomalous and left handed propagation
In this this paper we quickly derive the Kramers-Kronig relations from simple causality considerations and propose a simple way to implement them using the Fast Fourier Transform. This work focuses on how to make these relations a usable tool even when their conditions of validity are not strictly r...
