The Modulated Scatterer Technique (MST) has shown promise for application in microwave imaging, electric field mapping, and materials characterization. It is difficult to reliably detect the modulated scattered signal, due to the small size of the MST elements. Increasing the modulation depth (a parameter related to how well a scatterer modulates an incident signal) may improve the detection of the...
Detection and evaluation of corrosion in reinforcing steel bars (rebars) commonly used in cement-based structures is an important ongoing concern. Embedded sensor technologies hold promise for this purpose. In recent years, modulated scatterer technique (MST) has shown great potential as an embedded sensor technology. The first step in evaluating the potential of embedded MST for rebar corrosion detection...
The modulated scatterer technique (MST) has shown promise as an embedded sensor technique for materials characterization and flaw detection. MST is based on illuminating a loaded scatterer/probe, usually a dipole antenna loaded with a PIN diode, with an electromagnetic wave. By detecting the backscattered (reflected) wave, information about the material properties in the vicinity of the probe can...
