Electromagnetic Response of Layered Dielectric Structures to Pulsed Acoustical Action
The process of elastic wave propagation in the inhomogeneous sample with the known stress-strength properties is numerically modeled. The stress intensity distribution over the sample having a defect is calculated for different moments of time. The calculated stress intensities are compared with the experimentally measured parameters of electromagnetic signals arising in the model layered system under mechanoelectrical transformations accompanying the acoustic pulse propagation. The influence of the layered structure on the amplitude of the electromagnetic response is demonstrated experimentally for a serpentinite rock sample under deterministic action of the acoustic pulse.
