We propose a novel method using open-ended rectangular waveguide probe operating in K-band (18–26.5GHz) for inspecting impact damage and fibre texture of the CFRPs. Reflection coefficients are measured by means of vector network analyser (VNA) at different points in X and Y directions (C-scan). Three different energy impact samples: 4J, 6J, and 10J are tested. The optimal scanning step sizes with...
Electromagnetic imaging currently occupies a vital role in various disciplines from engineering to medical applications. These roles are based upon the fundamentals of Electromagnetic (EM) fields and their relationship with the material properties under evaluation. A new system based on a Giant Magneto-Resistive (GMR) sensor array was built to capture the scattered EM signal returned by metallic objects...
The detection of concealed weapons is one of the biggest challenges facing homeland security. It has been shown that each weapon can have a unique fingerprint, which is an electromagnetic signal determined by its size, shape, and physical composition. Extracting the signature of each weapon is one of the major tasks of any detection system. In this paper, feature extraction of a new metal detector...
