Автор:Aleksey Zakharenko Год: 2010 Издание:LAP Lambert Academic Publishing Страниц: 84 ISBN: 9783843364034 This book addresses to theoretical investigations of shear-horizontal surface acoustic waves (SH-SAWs) propagating in composites of class 6 mm which can possess piezoelectric and piezomagnetic phases. Applying different electrical and magnetic boundary conditions in the theoretical treatments, wave characteristics of seven new SH-SAWs are obtained in explicit forms. It was found that the new SH-SAWs can have both piezoelectric and piezomagnetic properties. Also, the analytically obtained exact formulae for the new SH-SAW velocities can demonstrate dependencies on the squared speed of light in a vacuum. It was also found that the new SH-SAWs can be coupled with the surface Bleustein-Gulyaev waves and bulk acoustic waves for the piezoelectric and piezomagnetic phases. Calculations of the new SH-SAW characteristics were performed for sample two-phase composites BaTiO3-CoFe2O4. It is thought that the obtained results can be useful for complete understanding of wave processes in composite ...
