  • Dielectric constant - also known as static relative permittivity, the relative permittivity for a material with a frequency of zero
  • Dielectric devices - devices that provide insulation and can be polarized by the application of an electrical field
  • Dielectric losses - the losses of electromagnetic energy in a dielectric material
  • Dielectric materials - materials that are poor conductors of electricity but are good at maintaining electrostatic fields, measured by how easily a material polarizes in response to an electrical field
  • Dielectric substrates - material substrates to devices offering high dielectric susceptibility
  • Dielectrophoresis - or DEP, a situation in which force is exerted on a dielectric particle when it is in the range of a non-uniform electric field
  • Electrokinetics - electrical effects that occur in heterogeneous fluids
  • Electrostriction - the property of all electrical non-conductors that cause them to alter their shape upon the application of an electric field
