Abstract

The effect of barrier layers with a generalized dielectric response on the measurement of the dielectric properties of materials are investigated, using the cluster model of relaxation to represent both the bulk and barrier properties. It is shown that the Maxwell-Wagner response is a limiting case and only applicable when the series elements are perfect, non-dispersive capacitors and resistors. A number of experimentally investigated systems are examined and it is shown that there is clear evidence for the proposed model in a wide range of applications.
