| Abstract: | Granular films whose bands of plasma resonance are anisotropic are obtained by vacuum deposition of indium on rough surfaces
of NaCl and KCl single crystals. On electron-microscopic pictures of samples, sections whose granules form chains with distances
between them somewhat larger than the distances between the ganules in the chains are found. The maximum of the absorption
band in polarized light along the chains is shifted into the low-frequency region of the spectrum in comparison to the abosorption
band’s maximum in polarized light perpendicular to the chains. A second band of plasma resonance whose frequency is equal
to the free-running frequency of electrons in a granule is found in the high-frequency region of the spectrum.
