Overview

Method determines dielectric constants of polar liquids, suggesting high accuracy in measurements.

Key Points

  • To describe a method for measuring the refractive index of polar liquids using a cavity resonator.
  • Measure resonance curve of an H 01 resonator with an axial capillary of liquid.
  • Calculate independent value of dielectric constant κ.
  • Tested method on water at 21° C.
  • Measured refractive indices for water were 6.25, 6.30, and 6.35.
  • The method achieved ±1% accuracy in measuring dielectric constants.
