Modeling of Magnetoelectric Effects in Composites

This book brings together numerous contributions to the field of magnetoelectric (ME) composites that have been reported so far. Theoretical models of ME coupling in composites relate to the wide frequency range: from low-frequency to microwave ones and are based on simultaneous solving the elastostatic/elastodynamic and electrodynamics equations. Suggested models enable one to optimize magnetoelectric parameters of a composite. The authors hope to provide some assimilation of facts into establish knowledge for readers new to the field, so that the potential of the field can be made transparent to new generations of talent to advance the subject matter.

Numerous step-by-step tutorials help the reader to estimate the peak values of magnetoelectric parameters of a composite Explicit expressions for magnetoelectric coefficients enable finding an optimal composition for obtaining a strong magnetoelectric effect In-depth analysis of enhanced magnetoelectric coupling in the frequency regions corresponding to mechanical and magnetic resonance suggests application of composites at overlapping of acoustic and magnetic resonances due to giant magnetoelectric coefficients Provides a strong combination of theoretical background combined with applications Includes supplementary material: sn.pub/extras
