WebThe Kramers-Kronig relations imply that observing the dissipative response of a system is sufficient to determine its in-phase (reactive) response, and vice versa. The formulas … Web26 de fev. de 2024 · The Kramers–Kronig relation provides a physical connection between the spectral variation of the (real) refractive index and the absorption …
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 ... WebClosed form expressions of the Kramers-Kronig and of the multiply subtractive Kramers-Kronig relations are derived to predict the real part of the refractive index from the …
WebOur approach is based on space-domain Kramers-Kronig relations that transform the spatial variation in intensity to the spatial variation in phase. We demonstrate two-dimensional holographic imaging and three-dimensional refractive index tomography of microscopic objects and biological specimens from intensity images measured with an … WebOn the applicability of Kramers-Kronig relations for ultrasonic attenuation obeying a frequency power law Authors KR Waters 1 , MS Hughes , J Mobley , GH Brandenburger , JG Miller Affiliation 1 Department of Physics, Washington University, St. Louis, Missouri 63130-4899, USA.

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…
