Paper Abstract

The recent progress in creation of materials with negative refractive index inaccessible for natural substances show all-important role of the multi-phase materials in modern technology. In the present work the approach for calculating of effective properties is considered for multi-component composite materials with variable configurations and concentration of inclusions [1]. The approach is based on interpolation formulas obtained between the rigorously calculated limiting borders [2]. The general merit of the model is the ability to obtain algebraic formulas for complicated properties with the vectors of electrical, thermal, magnetic, etc. fields directed along the different axes [3]. The examples of application of the above model are given for the analysis of multi-phase states in the vicinity of pressure-induced phase transition. The model was used for a set of semiconductor compounds like PbX, SmX (X - Te, Se, S), iron ore, etc. [4]. The program for calculation of different electrical, thermal, mechanical etc. properties of n-phase systems with variety of configuration and concentration of phase inclusions has been created, which may be applicable for real multiphase systems.
