On the kramers-kronig relations
WebKramers-Kronig relations The Kramers-Kronig relations give a way how the real and the imaginary part of a function are related to each other. Of course you can’t use the relations for all function, there are a few conditions that have to be met. When the relations are used on the function X(!) which is the Fourier transform of the function 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…

WebUnder certain conditions the Kramers-Kronig relations may be approximated by rather simple equations. For linear viscoelastic materials, for instance, the following approximate relations were obtained for the components of the complex dynamic shear modulus, G * (iω) = G′ (ω) + iG″ (ω) = G d (ω) exp iδ (ω): WebCausality and the Kramers-Kronig relations. Causality describes the temporal relationship between cause and effect. A bell rings after you strike it, not before you strike it. This means that the function that describes the response of a bell to being struck must be zero until the time that the bell is struck. Consider a particle of mass moving ...
