Debye's equation is a mathematical equation used to model the dielectric behavior of materials as a function of frequency. To use Debye's equation in Matlab or Python to model experimental data, follow these steps:

Collect experimental data for the dielectric behavior of the material as a function of frequency. This data can be obtained from various sources, such as literature or experimental measurements.

Define the values for the parameters in Debye's equation. These parameters include the dielectric constant of the material, the relaxation time of the material, and the permittivity of free space.

Implement Debye's equation in either Matlab or Python using the parameters defined in step 2. The equation is as follows:

ε(ω) = ε'∞ + (εs - ε'∞)/(1 + (iωτ))

Here, ε(ω) is the complex dielectric constant at frequency ω, ε'∞ is the high-frequency limit of the real (dispersive) part of the dielectric constant, εs is the static relative permittivity, τ is the relaxation time, i is the imaginary unit, and ω is the angular frequency.

Use the implemented equation to fit the experimental data, i.e., adjust the values of the parameters until the modeled results match the experimental data as closely as possible.

Evaluate the quality of the fit by calculating the sum of squared residuals (SSR) or the coefficients of determination (R2).

Optionally, plot the experimental data and the modeled results to visualize the fit and compare them.

By following these steps, one can use Debye's equation in Matlab or Python to model experimental data and gain insights into the dielectric behavior of the material under investigation.
