The book focuses on the main characteristics of coupled electromagnetoelastic waves, surface Rayleigh waves in piezoelectric and magnetoelastic media, Lamb waves and shear waves in piezoelectrics. The authors discuss the criteria of dielectric and piezoelectric breakdown. All topics of the book receive full coverage at the modern mathematical level. The book is intended for professionals working in the field of mechanics of deformed solid body, acoustics and defectoscopy, and for postgraduates and students specializing in physics and mechanics of continuous media.
