DISPFIT
Dispersive fitting tool based on genetic algorithm (GA) optimization.
Layout of the DISPFIT tool.
Product description
GA-based optimization tool to obtain parameters for the different dispersive models (Debye, Lorentz, Drude, and the combination of Drude-Lorentz) for a given material (user-defined or imported from a text file).
Features
- Initial data can be loaded from text file or specified directly by the user
- Load IT’IS material database
- Specify initial and final frequency and number of samples
- Specify target error, maximum search time and number of poles
- Graphic representation of initial data and proposed fitting curves superimposed
- X-axis can display frequency or wavelength
- Y-axis can display Conductivity or Imaginary part of Permittivity
- Best fit can be copied directly into simulation settings
Applications
- Obtain frequency dependent material parameters for wideband simulations
