Review of simple ideas of polarisation emphasising the frequently employed assumptions/approximations.

Equivalent circuit model of a dielectric. Frequency dependence. Standard definitions of relevant quantities.

Basic sources of contributions to polarisation in dielectrics.


(Derivation of some basic relationships relating to polarisation)

Introductory handout


What you need to know

You need to ensure that you are familiar with the standard concepts and definitions regarding polarisation in dielectric media. You need to understand the details of the equivalent circuit model of a dielectric and know how this leads to the definitions for the loss tangent and complex capacitance and permittivity.
