Modeling the Wave Motion in Magneto-electro-elastic Materials
Strain-mediated magneto-electric materials, also known as magneto-electro-elastic materials, have received tremendous attention due to their potential in realizing electric-field control of magnetism. More importantly, novel wave propagating behavior can be found in such materials, which involves coupling between elastodynamics and electrodynamics. Yet little work has been done on numerical simulations that allow us to look into the wave phenomena in these materials. This dissertation is devoted to the development and validation of finite element methods that are capable of handling this coupling, with an emphasis on the acoustically-driven electromagnetic radiation from piezoelectrics and piezomagnetic media.
