Dielectric properties of materials


ECTS Credits : 2

Duration : 21 hours

Semester : S8

Person(s) in charge:

Emilie GAUDRY, Associate Professor, 


Dielectric materials, properties, applications


Atomic and molecular arrangements, structures and defects
Electric and thermal properties of materials

General objective :

Learn the necessary basic knowledge of physics to follow the technological innovations in the field of dielectric materials

Program and Contents:

Dielectric materials are experiencing a considerable development, especially due to the growing impact of technology related to electronics: a mobile phone can hold up to several hundred capacitors! In addition to their applications in the field of electronics (high performance capacitors, insulators), these materials are used for their piezoelectric properties (shock and acceleration detector, sonar, loudspeaker, etc.), for their pyroelectric properties (fire detector, infrared imaging), or for their applications in optics (optic fibers, birefringent materials).

This course is divided into 6 chapters:

  • Polarized materials
  • Polarization mechanisms.
  • Frequency dependence of polarization, relaxation and resonance phenomena.
  • Real dielectric materials, losses, breakdown.
  • Ferroelectric piezoelectric, pyroelectric materials.
  • Optical properties of dielectric materials.



Description and operational verbs


Name and describe the different types of dielectric materials.


Link the macroscopic properties of dielectric materials with polarization mechanisms in order to explain dependences (temperature, frequency) of dielectric macroscopic quantities.


Describe the main technological applications of dielectric materials.


The first test, quite short, is to evaluate students' knowledge and understanding of the course and their capacity to use little and easy reasoning.
The second test will be a longer problem in order to test analytical insight of students and their capacity to deal with a complex system.


The oral talk test both abilities to analyse and to summarize on a determined subject. Their oral abilities to communicate on a scientific subject will also be tested. The subjects will be chosen among dielectric applications.


The course assessment will consist of a midterm, a longer final test and an oral presentation by the students on a subject selected from applications of dielectric materials.
