Polarization P and Relative Permittivity <emphasis role="italic">∊<subscript>r</subscript></emphasis> Dielectric materials become polarized in an electric field, with the result that the electric flux density D is greater than it would be under free-space conditions with the same field intensity. A simplified but satisfactory theory of polarization can be obtained by treating an atom of the dielectric as two superimposed positive and negative charge regions, as shown in
