Abstract
The electromagnetic response to impact acoustic excitation in concrete is studied theoretically and experimentally. It is revealed that the amplitude-frequency characteristic of the response depends on the dimensions and location of inclusions in the material. A physical model of acousto-electromagnetic conversion in concrete is suggested. The amplitude-frequency characteristic is computed on the basis of an equivalent circuit. It is found that the computed and measured data agree, which supports the physical model.
