Abstract
An electromagnetic-acoustic transducer (EMAT) of novel design is used to excite and detect only those resonant modes of a cylinder that have a specific, integral number of nodes on the circumference. Because the nodal pattern is fixed and the coupling between the cylinder and transducer is weak, the resonances have very well defined frequencies which allow applications that include measurements of accurate shear wave velocities in commercial alloys, case depth in hardened steel shafts and axial stress in solid cylinders
