Media 8, No. 4, 913-941 (2013). Summary: We determine, in dimension three, the effective conductivities of non periodic and high-contrast two-phase cylindrical composites, placed in a constant magnetic field, without any assumption on the geometry of their cross sections. Our method, in the spirit of the H-convergence of Murat-Tartar, is based on a compactness result and the cylindrical nature of the microstructure. The homogenized laws we obtain extend those of the periodic fibre-reinforcing case of [M. Briane and L. Pater, J. Math. Anal. Appl. 393, No. 2, 563–589 (2012; Zbl 1276.35021)] to the case of periodic and non periodic composites with more general transversal geometries.
