Physics of Dielectrics

Lecturer:

Zdeněk Bryknar (gar.)

Tutor:

Supervisor:

Department of Solid State Engineering

Synopsis:

Electrical, thermal, and mechanical properties of dielectrics and switching of polarization in ferroelectrics are described in details. Interaction of electromagnetic field with dielectric materials is studied in a wide frequency range from point of view of classical and quantum physics.

Requirements:

It is recommended to complete Solid State Theory lecture (TPL1 at FNSPE).

Syllabus of lectures:

1. Lorentz field, local field and Clausius-Mosotti equation 2. Polarization mechanism 3. Dielectrics in a-c field 4. Kramers-Kronig relations 5. Permittivity relaxation, Debye's formulas 6.
