During acoustic imaging, the spaces between the cracks helped to reflect ultrasound and create the anomaly seen in Figure 1.
By placing the metamaterial between the imaging device and the object being imaged, we were able to more than double the resolution of the acoustic imaging -- from one-half the sound's wavelength to greater than one-fifth.
These constraints make acoustic imaging of MLCCs after reflow or wave soldering an important tool.
Acoustic imaging has limitations with high-glass-content materials because of its sensitivity to air gaps.
In other words, the acoustic imaging technique does not generate false positives indicating damage where there is none.
