Paper Abstract

For composite media some recent phenomenological approaches to treating dielectric properties in the long-wavelength limit are considered. Among the problems discussed are the features of media with close-packed particles, role of topology and bounds for the effective dielectric function. As an example, we consider close packing of submicron TiO2 particles. An analysis of the near-normal reflection spectra is made. Using the Kramers-Kronig relation and the modified Avary method, we obtained a composite dielectric function in far IR. When modeling the dielectric properties of the system studied, we used Bergman's representation.
