We report on the calculation of low-frequency Raman scattering by longitudinal acoustic phonons in superlattices. The phonons are treated as elastic waves propagating in a continuum and their mode patterns are calculated by a transfer-matrix method. The electromagnetic propagation is calculated neglecting reflections and refractions at the interfaces, through the use of the same index of refraction for both constituent materials. The use of a complex refraction index allows for absorption effects to be included. The suitability of the numerical calculation for modeling superlattices is demonstrated.
