MODELLING DIELECTRIC RELAXATION WITH NEURAL NETWORKS
Nicola Barbalace · Messanae Universitas Studiorum (University of Messina) · 2009
ABSTRACT. We describe a software model for media with dielectric relaxation. In par-ticular, a model identification is used to measure the phenomenological coefficients which occur in a mathematical description of dielectric relaxation phenomena in electromagnetic media. The identification is developed in order to substitute laboratory dielectric measure-ments on PMMA and PVC at different frequencies and at fixed temperature so as to obtain the phenomenological coefficients as a function of the frequency. 1.
