Nondestructive testing (NDT) methods are widely used in the rail industry to detect rolling contact damage (RCD) defects to ensure railway safety. With the need of monitoring millions of miles of rail tracks more effectively and efficiently that lead

Nitrogen contamination of weld material affects mechanical properties and results in small change of the electric conductivity. This small difference of resistivity needs to be measured since the material property is affected by the nitrogen contamin

Martensitic grade stainless-steel is generally used to manufacture steam turbine blades in power plants. The material degradation of those turbine blades, due to fatigue, will induce unexpected equipment damage. Fatigue cracks, too small to be detect
Defective adhesive bonds pose significant threats towards structural integrity due to reduced joint strength. While the nature of the adhesion of two solids remains poorly understood since adhesion phenomenon is relevant to so many scientific and tec

Metamaterials have been increasingly used in the past few decades in the design of novel microwave circuits and sensor systems. This paper deals with the design of a split-ring resonator (SRR) sensor for microwave nondestructive evaluation (NDE) appl

Microwave NDE techniques rely on the ability to propagate through Fiber Reinforced Polymer (FRP) composites and provide information about the structural integrity of composite materials. Time reversal (TR) property of the wave equation offers an effe

Quantitative assessment of the reliability of defect classification is critical in non-destructive evaluation (NDE) applications. Particularly in automated data analysis systems, such a measure enables the system to monitor its own performance and au

Time-reversal (TR) focusing is based on the fact that when a wave solution is reversed in time and back propagated, it focuses back at the source. TR techniques using microwave measurements have proved to be promising for radar detection and defect i
