Hybrid modes exist as a consequence of acoustic and optical waves having to satisfy the boundary conditions at an interface or at a surface. The author begins the description of hybrid modes in nanostructures with an account of modes in a non-polar, free-standing slab. This chapter includes long-wavelength assumption decouples acoustic and optical modes; isotropy decouples LO and TO modes; s and p modes; acoustic hybrid modes: Love waves, Lamb waves, guided modes, Rayleigh waves; the boundary condition u = 0 for optical modes; the sTO mode; double hybrid: LO and pTO modes; and energy normalization.Less

Assumptions: long-wavelength, isotropy, u = 0 for optical modes. This chapter considers a slab of polar material bounded in the z direction at z = ±L/2 and unbounded otherwise. It covers: triple hybrid model for optical modes; energy normalization; reduced boundary conditions; barrier modes; dispersion and wave patterns; acoustic hybrids; sTA and p modes; families of guided p modes; and interface acoustic waves.Less
