On the Causes of Possible Errors in the Solution of Scattering Problems,r the experienced reader. As such examples, we shall use the solutions of the problem of scattering by elastic spheres and cylinders. Here the exact solution exists and therefore it becomes easy to explain the cause of the mistake. In more complicated scattering problems, for example, by a system of

Peripheral Waves in the Scattering of a Plane Acoustic Wave Obliquely Incident on a Solid Elastic Cdispersion curves of the phase velocities is presented. In a series of papers the observation of supplementary (guided) waves that propagate along helical paths has been described and their behavior has been interpreted.

Resonance Scattering by Elastic Bodies of Cylindrical Shape,e same kind are grouped into families (the Regge poles). Using the positions of the isolated modal resonances, the phase and the group velocities of the peripheral waves revolving around the elastic body are found. A correspondence between the resonance frequencies of partial waves and the eigenfrequencies of the elastic body is established.

Peripheral Waves in the Scattering by Elastic Cylinders and Spheres,he case of aluminum cylinder and sphere immersed in water. The incident plane wave generates the Rayleigh wave and transverse Whispering Gallery waves in the cylinder and the sphere. It is found that these waves depend weakly on .., while strongly depending on ...

Pulsed Resonance Identification Method,xhibits good capabilities for detection, characterization, and classification of resonances. This approach allows one to reduce the time needed for an experimental investigation, admittedly at the expense of the exactness of the result.
