Abstract
An overview is given of the EMUS transduction technique, its physical foundations, transducer construction, laboratory developments and applications. The flexibility in transducer construction permits the excitation of a large variety of bulk waves and guided wave modes. Important application fields for the EMUS transducers are nondestructive testing with Rayleigh waves, SH waves and shear waves with normal incidence since, for these wave types, conventional excitation through a couplant suffers serious drawbacks.
