The paper reveals the effect of imperfection of solid-state dielectric samples on the parameters of the electromagnetic response under exposure of the test object to deterministic acoustic impact. The patterns of changes in the parameters of electromagnetic signals with variations and an increased electric field vector with respect to the defect–sample contact are provided. It is shown that the amplitude-frequency parameters of the emitted electromagnetic signals are directly related to the acoustic impedance and conductivity of the contacting medium and defect. The amplitudes of the electromagnetic responses are found to correspond to the distribution of mechanical stresses arising in an imperfect system during acoustic pulse propagation in time and space determined through mathematical modeling. The paper presents data on changes in the electromagnetic signal parameters for model defects of an increased size in samples of similar type.
