Abstract
Oscillations on the surface of artificial and natural inhomogeneous media (viz., electromagnetic crystals, disordered percolation systems, polycrystalline substances, and multicomponent dielectrics) are considered. Special attention is paid to the influence of correlation and fluctuation effects on the spectra of surface waves in the three last cases. For example, a pseudogap in the vicinity of the percolation threshold is observed in the oscillation spectrum at the interface between a metal-insulator composite and a conventional insulator. In the case of the interface between a metal-insulator composite and a metal, the effect of the Fermi-liquid interaction of electrons in the metal on the surface excitation spectrum is studied. It is shown that taking into account this interaction leads to a frequency shift in the surface wave, which is proportional to the Landau coefficient A 0. The frequency shift obtained for surface oscillations of polycrystals is due to fluctuations of anisotropy of individual crystallites. An analogous shift in the case of a multicomponent insulator is associated with polarizability fluctuations of molecules.
