Modelling and Analysis of Fractional Capacitors

Madhab Chandra Tripathy, Sribatsa Behera

The aim of the paper is to explore both theoretically and experimentally the modelling of different in-house developed PMMA coated fractional capacitors [5]. The design realization and behaviour of Polymethyl methacrylate (PMMA) coated probe has been studied in different polarizable medium like Ph 9.2, Ph 4.0, tape water and distilled water. Different frequency responses are obtained and a corresponding mathematical model has been proposed from experimental data. The parameters of modelled data have been found using least square estimation technique.
