Summary:Title screen
Two-dimensional mathematical model of dielectric specimen was used to determine the capability of mechanoelectrical transformations (MET) method to localize macrodefects. Amplitude and phase characteristics of response signal analytical representation were used as response parameters. Three different types of short radiofrequency pulses were chosen for the excitation. A short sin curve of a single period interval is most useful to search the position of the defect, whilst pulses of higher frequencies and are better for location depth evaluation.
