Possibilities for Increasing the Efficiency of Contactless Emitters of Acoustic Waves

Acoustic Methods


An electromagnetic-acoustic emitter has been designed that is capable of exciting widespectrum acoustic waves on a narrow section of the surface of metalware with a low voltage across the inductor. An engineering solution has been proposed that allows one to place emitter’s inductor directly on the surface of an article.
