This paper presents the application of a homogenisationtechnique, based on the multi-scale expansion theory, to theanalysis of heterogeneous materials constituted of magneticinclusions dispersed in a dielectric lattice. The role of the shapeand dimensions of the inclusions is analysed with reference to theeffective electromagnetic properties and energy losses. Theinvestigation is extended to the influence of flux waveforms withharmonic distortion, focusing the attention on the energy lossdependency on the harmonic content.
