Amazing. Thank you.DrDu said:Yes, it is possible to calculate the permittivity of a substance ab initio.
The theory is not elementary:

In principle, the dielectric function in dependence of frequency and wavenumber also determines the permeability.
Permittivity and permeability are physical quantities that describe the ability of a material to support the formation of an electric and magnetic field, respectively.
No, permittivity and permeability are not constant values. They can vary depending on the material and the conditions in which they are measured.
Yes, permittivity and permeability can be predicted to some extent. However, they are also affected by many factors, making it difficult to accurately predict their values.
Permittivity and permeability are related through the speed of light in a vacuum, as they both play a role in determining the speed of electromagnetic waves.
Permittivity and permeability are important because they are fundamental properties of materials that affect their behavior in electromagnetic fields. They are also used in many practical applications, such as in the design of electronic devices and telecommunications systems.
