Descrição: The paper is devoted to the numerical simulation of the electromagnetic field propagation in a complex heterogeneous material with the direct resolution of its microstructure. The electromagnetic field dynamics is described using full non-stationary system of Maxwell’s equations. Geometrical model of the material structure is developed using well-known Lyubachevsky-Stillinger sphere packing algorithm and event-based molecular-dynamic simulation approach. Comparison between simulation results in heterogeneous material and in effective homogeneous one is presented and discussed. The results of the simulation allow to obtain both the full structure of the electromagnetic field distribution and the assessment of the influence of the material inhomogeneities on the electromagnetic field propagation. Besides, the effective properties of the medium are computed using simulation results.
