Objectives of the Course The objective of this course is to extend the foundational knowledge gained in EEE673 Physics of Dielectrics I with advanced topics, providing graduate students with an in-depth understanding of relaxation mechanisms in dielectric materials, ferroelectric/piezoelectric/pyroelectric phenomena, degradation processes in high-voltage insulation materials, and current developments in nanocomposite dielectrics. Students will be able to perform material characterisation using dielectric spectroscopy methods and critically evaluate research trends in the literature.
Course Content Complex dielectric permittivity and loss mechanisms. Debye relaxation and extended models (Cole-Cole, Davidson-Cole, Havriliak-Negami). Temperature-dependent dielectric behaviour; Arrhenius and VTF models. Ferroelectric materials: phase transitions, hysteresis, and Curie-Weiss law. Piezoelectric and pyroelectric materials. High-voltage insulation materials: solid, liquid, and gaseous dielectrics. Dielectric ageing and degradation; partial discharge and electrical treeing. Polymeric dielectrics: XLPE, EPR, and silicone rubber. Nanocomposite dielectrics. Dielectric spectroscopy methods: FDS and PDC measurements. Current research trends and energy storage applications.
Course Methods and Techniques The course is primarily lecture-based, supported by problem-solving sessions focused on mathematical modelling of dielectric phenomena. Case study analyses selected from the high-voltage engineering and materials science literature are used to discuss the practical implications of theoretical knowledge. Critical in-class evaluation of current research papers develops students' scientific reading and assessment competencies.
