WebThe Kramers–Kronig relations relate ε1 (ω) and ε2 (ω) so that if either of these functions is known as a function of ω the other is completely determined. Because of the form of these relations (Eqs. 6.1 and 6.2), it is clear that the main contribution to ε1 (ω) comes from the behavior of ε2 (ω 0 ) near ω 0 ≈ ω due to the resonant denominator in these equations.
