Reflection of pulses at oblique incidence from stratified dispersive media

The reflection coefficient is calculated at normal and oblique incidence for a sine-squared pulse with the middle layer having a frequency dependent complex permittivity. The two important results of the theoretical investigation are the importance of the frequency dependence of the complex dielectric constant in pulse propagation studies as well as the unique effect that occurs at some angles of incidence at parallel polarization in which the power from the second interface exceeds the primary reflection from the first interface.
