Web20 de out. de 1997 · Unlike the Kramers-Kronig dispersion relations, they only require measurements over a finite frequency range. They can provide highly accurate interpolation formulas for the real part, given its value at a few selected frequencies and given the imaginary part over a range of frequencies. Received 5 December 1996 WebThe Kramers–Kronig relations (KKR) are relations between the real and imaginary part of the dielectric function. They are of a general nature and are based on the properties of a complex, analytical response function f (ω) = f 1 (ω) + if 2 (ω) fulfilling the following conditions:1 · The poles of f (ω) are below the real axis. View via Publisher WebIn fact, it is not at all surprising that a Kramers–Kronig-like relation should exist for the present situation; the expression is linear in the field and the physical system is causal, and thus the reasoning leading to the usual linear Kramers–Kronig relation is directly relevant to the present situation. how much of my fers retirement is taxable
