Abstract: Early evaluation through the detection of surface defects in welds is essential to ensure the quality of weldments. In this study, considering the complexity of weld surface inspection, we ...

Abstract: A new planar structure for the implementation of highly sensitive single-frequency microwave sensors is proposed. The key aspect to obtain high sensitivity is to generate closely spaced ...

Semiconductors are used in devices such as memory chips and solar cells, and within them may exist invisible defects that ...
