This chapter discusses how the mixing process affects the temporally dispersive properties of materials. The time variation of the electromagnetic phenomena under consideration is very simple. It is sinusoidal, and the frequency of the wave variation is a measure for the time derivatives that are needed in Maxwell equations. Use of complex vectors helps to eliminate totally the time-dependence in the field quantities, and admittedly the remaining equations are easier to solve than the original time-varying system.
