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.
