Onsager theory of dielectrics Onsager theory of dielectrics[′ȯn‚säg·ər ‚thē·ə·rē əv ‚dī·ə′lek·triks] (electricity) A theory for calculating the dielectric constant of a material with polar molecules in which the local field at a molecule is calculated for an actual spherical cavity of molecular size in the dielectric using Laplace's equation, and the polarization catastrophe of the Lorentz field theory is thereby avoided. |
