Ks. Srivastava et al., DISPERSION-RELATION FOR COUPLED SURFACE PLASMON-PHONON-POLARITON MODES IN POLAR SEMICONDUCTORS FOR PLANE SURFACES, Indian Journal of Pure & Applied Physics, 32(4), 1994, pp. 353-357
The coupled surface plasmon-polariton modes have been studied for plan
e interfaces of two isotropic dielectric media. The effect of spatial
dispersion is incorporated in our study using Bloch's hydrodynamical m
odel. The dispersion relation for plasmon-phonon-polariton surface mod
es has been derived. The coupled surface phonon-polariton modes have a
lso been studied as a special case.
