Work is devoted to development of mathematical model for the analysis of reradiation of acoustic impulses in energy of electromagnetic responses of layered and defective structures. Calculation of arising electromagnetic fields is presented at any arrangement of two extended defects with double electric layers, but with the different direction of distribution of the determined acoustic impulse. As model used the simplified representation of the loaded defect in the form of an air cavity – crack. For the solution of the differential equation of capacity of the condenser Runge-Kutt’s numerical method was used. The solution of two tasks, namely dependence of current of shift of i(t) on the size of external indignation ξ∙d and on a charge of q(t) is provided in work. The graphical representation of distribution of an arising electromagnetic field is considered at mutually perpendicular impact on a sample with defects an acoustic impulse, shifts of facings of the condenser and change of their capacity in time. Calculations for the given models showed that acoustoelectric transformations are resulted by reradiation on double electric layers of energy of influencing acoustic impulses in energy of electromagnetic responses.
