On the kramers-kronig relations
WebKramers-Kronig Relations Francesco Cicciarella (Dated: March 7, 2014) In the following pages, we will examine the mathematical properties of the dielectric permittivity as a function of the frequency for rapidly variable elds and we will derive the Kramers-Kronig relations, which mutually relate the real and imaginary part of the permittivity. WebThe Kramers–Kronig relation provides a physical connection between the spectral variation of the (real) refractive index and the absorption coefficient. In particular, a sharp spectral …

WebApart from being of great importance in high energy physics, statistical physics, and acoustics, at present the Kramers-Kronig relations are basic and widely-accepted tools … The Kramers–Kronig relations are bidirectional mathematical relations, connecting the real and imaginary parts of any complex function that is analytic in the upper half-plane. The relations are often used to compute the real part from the imaginary part (or vice versa) of response functions in physical systems, because for stable systems, causality implies the condition of analyticity, and conversely, analyticity implies causality of the corresponding stable physical system. The relatio…
