Electromagnetic modes are studied in the long wavelength limit, with a nonlocal dielectric tensor valid in this limit and at low temperatures and adaptable to type-l semiconductor superlauices, such as GaAs/GaAlAs alternative multilayers. The TM and TE modes are considered and dispersion relations are obtained respectively.
