Microwave Technique for Sizing Finite Cracks on Metal Surfaces using Open-Ended Rectangular Waveguides

Abstract

Two different microwave techniques for detecting fatigue or stress surface cracks in metals have been introduced. In both cases, an open-ended rectangular waveguide is used to scan over the metal surface under examination. Once a crack has been successfully detected, for both fracture analysis and repair considerations, sizing becomes the next important step. The models established for surface crack detection and their associated computer codes can be used to establish a useful crack sizing technique. The following describes a sizing technique for this purpose.
