Abstract
The complex permittivity of a three-component water-in-oil microemulsion was measured as a function of frequency, temperature, and volume fractions. A conductivity threshold, associated with a permittivity maximum, was observed and is explained in terms of percolation theory. The experimental value of the critical exponent of the frequency dependence of the permittivity, , is in good agreement with theoretical predictions.
