Effect of spatial dispersion on the change of the phase ofreflected light in CdS and CdSe crystals
Solov'ev L.E., Babinskii A.V.
An analysis is presented of the phase change produced when light is reflected from CdS and CdSe, based on the theory of spatial dispersion with allowance for the damping and for the surface layer. The existence of normal waves of optical and exciton type is observed experimentally.
