Abstract The equations of motion for the p-polarization field in a C/B/A/B/C-type five-layer heterostructure of polar crystals arc solved exactly for the interface optical-phonon modes. The eigenvectors arc obtained explicitly. The dispersion relation is derived and discussed in detail for sonic limiting cases. This work can be regarded as a generalization of the formation of that of Shi and Pan [Phys. Rev. B46, 4265(1992)].
