Frequency-dependent electric-field distribution, application

In the present study we have used a relatively new technique to study the morphology of these systems. Application of an alternating electric field to a multiphase morphology results in a frequency-dependent electric-field distribution due to the different permittivities and conductivities of dissimilar phases. Measured permittivity increases with decreasing frequency v = 0)/2ir, approaching a low frequency limit eQ as the field distribution transits from permittivity dominated to conductivity dominated.
