Summary: | This paper presents a model to calculate of effective permit ies for a 1 medium containing scatterers. With the strong fluctuation approach, the is developed to account for the scattering effect together with characteristics of multiple and of with distributed orientations, sizes, and DUC to a preferential direction in the orientation distribution, the medium is effectively 2 size distribution is described with a probability density function in terms of normalized volumetric sizes. Scatterer shapes have a genera] ellipsoidal form by arbitrary axial of correlation lengths which arc related to geometries of scatterers. In formulation, consisting solid ice, and gaseous inclusions is to derive with redistribution and structural Theoretical results arc in with experimental data 4.8 for saline ice warming and cooling cycles. effect between the increase of liquid brine and the of ellipsoidal scatterers at increasing temperatures explains the trend observed in measured data. Sensitivities of to structural physical parameters characterizing ice arc also studied. 1. INTRODUCTION Most natural media arc heterogeneous mixtures of materials with different phases, orientations, sizes, shapes. Physical and ural characteristics of medium st it uents are usual] y interdependent and influenced by al conditions such as temperature, radiation, moisture and precipitation. The composite media can characterized by effective perrnittivities, w] elect ic wave |
