(Note that this definition of \(\overrightarrow{b}\) is similar but not identical to the definition in [3].) In some materials, the material polarization depends linearly on the temperature as described by Equation \ref{3.1.1}. In other materials, more terms are needed to describe the dependence of the material polarization on temperature.
