Direct electromagnetic-acoustic conversion in ferromagnetic plates at arbitrary ratio between wavelengths of acoustic and electromagnetic oscillations
Source abstract
Abstract
Expressions describing elastic displacements due to Lamb waves of any type generated by fields (electromagnetic, acoustic, and thermal) of forces that are ruled by an exponential law are given. As an example, the generation mechanism controlled by magnetostriction and zero Lamb waves at an arbitrary ratio between the wavelengths of acoustic and electromagnetic oscillations are considered. An assumption that some modes of Lamb waves can be intensified owing to the electromagnetic-acoustic resonance in weakly conducting materials is put forward and justified.
