摘要

本文介绍了在外部脉冲声激励下改变带缺陷介电材料电磁响应参数的结果。结果表明，在电场和磁场中，电磁响应的振幅随外加场的特征而增加。根据介电材料中缺陷的性质和大小，电磁响应的幅频频谱会发生变化。

COMPARISON OF ACOUSTIC-ELECTRICAL NON-DESTRUCTIVE TESTING OF SOLID-STATE DIELECTRICS IN ELECTRIC AND MAGNETIC FIELDS

The paper presents the results of changing the parameters of electromagnetic responses in dielectric materials with defects under external pulsed acoustic excitation. It is shown that in electric and magnetic fields the amplitude of electromagnetic responses increases in accordance with the features of the applied fields. Depending on the properties and sizes of defects in dielectric materials, the amplitude-frequency spectra of electromagnetic responses change.
