Abstract
The equations of motion for the p-polarization field in a C/B/A/B/C-ty pe five-layer heterostructure of polar crystals are solved exactly for the interface optical-phonon modes. The eigenvectors are obtained exp licitly. The dispersion relation is derived and discussed in detail fo r some limiting cases. This work can be regarded as a generalization o f the formalism of that of Shi and Pan [Phys. Rev. B46. 4265(1992)].
