Tīmeklis克喇末-克勒尼希關係式（英語： Kramers–Kronig relations ）是數學上連結複面上半可析函數實部和虚部的公式。 此關係式常用於物理系統的線性反應函數。物理上因果關係（系統反應必須在施力之後）意味着反應函數必須符合複面上半的可析性。 反之，反應函數的可析性意味着相應物理系統的因果性。 TīmeklisThis video derives the Kramers-Kronig relationship for linear systems and shows how it is applied to electromagnetic materials. Applications and implication...

What did Kramers and Kronig do and how did they do it?

TīmeklisLe relazioni Kramers-Kronig, anche la relazione Kramers-Kronig (dopo i loro scopritori Hendrik Anthony Kramers e Ralph Kronig), mettono in relazione le parti reali e … Complex refractive index The Kramers–Kronig relations are used to relate the real and imaginary portions for the complex refractive index $${\displaystyle {\tilde {n}}=n+i\kappa }$$ of a medium, where $${\displaystyle \kappa }$$ is the extinction coefficient. Hence, in effect, this also applies for the complex … Skatīt vairāk 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 … Skatīt vairāk We can apply the Kramers–Kronig formalism to response functions. In certain linear physical systems, or in engineering fields such as signal processing, the response function Skatīt vairāk The conventional form of Kramers–Kronig above relates the real and imaginary part of a complex response function. A related goal is to find a relation between the magnitude and phase of a complex response function. In general, … Skatīt vairāk Hu and Hall and Heck give a related and possibly more intuitive proof that avoids contour integration. It is based on the facts that: • A … Skatīt vairāk • Dispersion (optics) • Linear response function • Numerical analytic continuation Skatīt vairāk http://www.lucabaradello.it/carcione/CCBCQ18.pdf cervical lymph node mapping
