WebAn analytic Distribution Function of Relaxation Times (DFRT) is derived for the fractal Finite Length Warburg (f-FLW, also called ‘Generalized FLW’) with impedance expression: Z f·FLW (ω) = Z 0 · tanh(ωτ 0) n · (ωτ 0) −n. τ 0 is the characteristic time constant of the f-FLW. Analysis shows that for n → 0.5 (i.e. the ideal FLW) the DFRT transforms into an … WebMar 6, 2024 · A W is the Warburg coefficient (or Warburg constant); j is the imaginary unit; ω is the angular frequency.
