Conditions and approximations for retrieving the complex permittivity and conductivity from the effective permittivity

2023
The electromagnetic characterization of materials, also known as dielectric spectroscopy, plays a key role in many applications. Its aim is to return either the effective permittivity or the effective conductivity over frequency for a sample of the material under investigation.
