A method is considered whereby Fresnel formulas for transparent, absorbing, and amplifying linear media are uniquely determined by passing to the plane-monochromatic-wave limit of an electromagnetic pulse, using the principle of causality and employing the analytical properties of the amplitude reflection coefficient of the Fourier components of the light pulse.
