The correct derivation is shown to give a formula that is identical to one found by Sillars, who calculated the effect of spheroidal particles sparsely distributed in an insulator. It is therefore preferable to
This is now commonly referred to as the Maxwell–Wagner–Sillars (MWS) effects (Maxwell, 1891, Wagner, 1914, Sillars, 1937). The interface effect not only occurs to the dielectric constant, but also to the electrical conductivity. In an attempt to capture the observed high conductivity and ...
It can be seen that both processes follow Arrhenius' law, with activation energies of 1.2 eV and 1.6 eV for the Maxwell-Wagner-Sillars and dipolar relaxation, respectively. It is evident from Figure 11 that the values of the relaxation rate [f.sub.max] of Maxwell-Wagner-Sillars are signific...
