Kramers-Kronig relationship computation by Gaussian quadrature
The Kramers-Kronig transformation has been extensively applied in optical spectroscopy to calculate the real component of an optical quantity from the imaginary component, such as the determination of the dispersive mode from a measurement of the absorptive mode and vice versa. In this paper, the Kramers-Kronig transformation is approximated.
