Theoretical investigation of magneto-electro-elastic metamaterials.

The properties of the multi-field coupling phonon-polaritons in magneto-electro-elastic metamaterials are studied theoretically on the base of the theory of the phonon-polaritons in the piezoelectric superlattices. The mechanism for multi−field coupling is analyzed. We discuss the factors that influence the properties of the multi−field coupling phonon-polaritons. We also study the negative magnetic permeability and negative refraction of the magneto-electro-elastic metamaterial. Some potential applications are also discussed. • The properties of the multi-field coupling phonon-polariton in magneto-electro-elastic metamaterials have been studied theoretically. •The mechanism for the multi-field coupling phonon-polariton coupling has been analyzed. •We have investigated the factors that influence the properties of the multi-field coupling phonon-polariton. •We have studied the negative magnetic permeability and negative refraction of magneto-electro-elastic metamaterials.
