  1. Difference between dielectric constant and dielectric function

    I'm confused by the definition of dielectric constant. We all know that dielectric is function of wavelength, because materials respond in different ways depending on the energy of the light. …

  2. What is the dielectric constant of a pure conductor?

    Feb 18, 2016 · Dielectric constant is the ratio of permittivity of a medium to the permittivity of free space. How to find dielectric constant of a conductor?

  3. electrostatics - Why is capacitance increased with a dielectric …

    Feb 12, 2019 · A dielectric with high permittivity $\varepsilon$ permits (requires) more polarization for a given field magnitude than a low permittivity one. More polarization means more charge …

  4. Is there any relation between dielectric constant of material and its ...

    Jun 10, 2021 · For conductors dielectric constant is infinite as electric field cant exist inside it .And conductors have very low resistance too .So is there any relation btw dielectric constant and …

  5. electric fields - What happens when a dielectric is inserted in a ...

    Dec 22, 2017 · However, when a dielectric is inserted, it reduces the field since the molecules of the dielectric align themselves in such a way that the moment is opposite to the external …

  6. electromagnetism - Dielectric constant or permittivity of metals ...

    Jan 9, 2016 · I'm wondering what the dielectric constant or permittivity of metals is --particularly copper. Do metals have an infinite permittivity?

  7. Is the polarity of light maintained after reflection from a dielectric ...

    Aug 2, 2022 · No, generally the absolute polarization angle isn't maintained. Consider for example, light incident at a shallow angle from the air onto the dielectric surface where the …

  8. electromagnetic radiation - Real and imaginary parts of dielectric ...

    According to Jackson, the real part of the dielectric is related to polarization and anomalous dispersion, while the imaginary part is associated with dissipation of energy into the medium.

  9. Reflection of electromagnetic waves from dielectric

    Feb 29, 2024 · So, most dielectric materials are modeled with a variable dielectric constant (or tensor) that accounts for polarization of the underlying medium (induced dipoles, etc.) …

  10. What exactly is breakdown voltage of air? - Physics Stack Exchange

    Breakdown electric field is just an aproximation and depends on a lot of factors. The breakdown voltage is the breakdown electric field multiplied by the distance. You are maybe asking about …
