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