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.


It is recommended to complete Solid State Theory lecture (11TPL1 at FNSPE).

Study Objective:


The aim of lecture is to understand the electrical, thermal, and mechanical behaviour of dielectrics and switching of polarization in ferroelectrics. The emphasis is devoted to interaction of electromagnetic field with dielectric materials in a wide frequency range.


Orientation in the effects and properties related to ferroelectric and multiferroic phenomena.
