Detection of Micro-Cracks on Metal Surfaces Using Near-Field Microwave Resonators

Non-Destructive Classification of Thai Cha-Nee Durian Maturity With Near-Field Reflection Mode Measurement Using a 3.4-GHz Microwave Sensor

“…In our research, microwave sensor based planar structure having advantages of light weight, compactness, and ease of use was decided, where configuration of microwave sensor, so called "Pencil-like shaped microwave sensor" including a 50- quarter-wavelength feeder and radiator, as shown in Fig. 7, which was developed from [28,29], where equivalent model is shown in Fig. 8.…”

Computer Simulation of Metal Surface Micro-Crack Inspection Using Pulsed Laser Thermography

“…At present, metal surface micro-cracks are usually detected by acoustic emission testing, ultrasonic testing, radiographic testing, magnetic particle testing, penetrate testing, and eddy current testing methods. The traditional detection technology has achieved good results in the detection of metal components which has low intensity, and improved product quality, reduced production cost and improved the social benefit of products [6][7][8][9][10][11].…”
