PronySeriesRetardation Class

Performs a fit with a Prony series to a retardation signal (general susceptibility), either in the time domain or in the frequency domain. If the signal is a time domain signal, it is assumed to be a retardation signal, i.e. is increasing with time (for instance strain at constant stress). If the signal is in the frequency domain, it is assumed to be a susceptibility, i.e. the real part is decreasing with frequency.

Properties
 NameDescription
Public propertyIsDielectricSpectrum If true, the flow term is multiplied with the dielectric vacuum permittivity in order to the the electrical conductivity.
Public propertyMaximalRetardationTime Gets or sets largest retardation time (the tau_retard of the last Prony term).
Public propertyMinimalRetardationTime Gets or sets smallest retardation time (the tau_retard of the first Prony term).
Public propertyNumberOfRetardationTimes Gets the number of retardation times, i.e. the number of Prony terms.
Public propertyRegularizationParameter Gets/sets the regularization parameter. Usually zero. The higher the value, the more are the prony coefficients smoothed out.
Public propertyUseFlowTerm If true, a flow term (fluidity, conductivity) is also fitted. Then in the result, the values for Fluidity and Viscosity are set.
Public propertyUseIntercept If true, an intercept (high frequency retardation value) is also fitted. In the result this is included as the Prony coefficient for retardation time zero.
