The amplitude structure of the sound pressure field and the vibrational velocity close to a liquid sphere when a plane wave is incident on it

The near field of the sound pressure and the components of the vibrational velocity when a plane wave is incident on a liquid sphere is calculated. The dependence of the field on the angles of incidence of the plane wave, the distance from the surface of the sphere, the wave dimensions of the sphere, and the frequency of the incident wave are analyzed. Different cases of the ratio of the velocities of propagation of the sound in the medium and in the material of the sphere for the same densities of the medium and the sphere are considered. It is shown that for specified wave dimensions of the sphere is a region where the amplitude characteristics of the field change sharply depending on the ratio of the wave impedances of the medium and the material of the sphere.
