Cole-Cole and Havriliak-Negami

Dispersion elements for broadened relaxation in dielectric and electrochemical spectra.

Cole-Cole (CC)

Three parameters: R, τ, α (dispersion exponent).

text
CC1{50,1e-3,0.8}

Symbol: single dispersion arc with α annotation (outline).

Havriliak-Negami (HN)

Four parameters: R, τ, α (asymmetric broadening), β (symmetric broadening).

text
HN1{50,1e-3,0.8,0.9}

Symbol: dual arcs with α,β label.

Series example

text
R0-CC1{100,1e-4,0.75}-HN2{100,1e-4,0.8,0.85}
ts
editor.setValue('CC1{50,1e-3,0.8}')

Validation enforces R, τ > 0; 0.3 ≤ α ≤ 1.0; for HN, 0 ≤ β ≤ 1.0.
