Effective Wave Number of Composite Materials with Randomly Distributed Inclusions

摘要

In this paper, the TCQ approach is applied to predict the effective wave number of composite materials with randomly distributed inclusions. The rotational addition theorems for scalar and vector spherical wave functions, and T-matrix are derived. Averaging over orientation on the governing equation for aligned TCQ model leads to the governing equation for the current problem that requires the averaged T-matrix of a single scatterer over orientations.
