Abstract :
The new technique for determination of complex permittivity of a liquid media by open-ended coaxial line probes, based on using metamaterial substrate with known characteristics, is proposed. Following this technique, determination of wide variations of complex permittivity of liquid from only amplitude measurements of a reflection coefficient in a finite frequency range in combination with fitting optimal thickness of a tested layer of liquid is possible.
