the losses in ac capacitors. All dielectrics (except vacuum) have
two types of losses. One is a conduction loss, representing the flow of actual charge through
the dielectric. The other is a dielectric loss due to movement or rotation of the atoms or
molecules in an alternating electric field. Dielectric losses in water are the reason for food and
drink getting hot in a microwave oven.
One way of describing dielectric losses is to consider the permittivity as a complex number
