Nondestructive testing of fiber array with multiple missing fibers

Abstract : Our goal is to detect defects in composite materials composed by multilayer planar plates with a periodic set of circular cylindrical fibers embedded in each layer. As a starter, the work presented is electromagnetic (EM) modeling and imaging of missing fibers within a fiber array standing in air. The multiple scattering method is utilized to analyze the electromagnetic behavior, and the corresponding imaging model is established directly from Lippman-Schwinger integral formulation. Standard MUltiple SIgnal Classification (MUSIC) and the proposed joint sparsity which borrows the idea of sparse theory are applied to retrieve the locations of missing fibers. Numerical results are provided to confirm availability and accuracy of EM modeling and defect imaging.
