Definition of Dielectric Constant

  • The significance of dielectric constant is a measure of a material's ability to increase the capacitance of a capacitor relative to a vacuum, reflecting the relative ability of a dielectric to store electrostatic energy in an electric field.

Definition of Dielectric Loss

  • Dielectric loss refers to the phenomenon where a dielectric heats up itself due to consuming part of the electrical energy in an alternating electric field.
  • Testing method: Vector Network Analyzer
