Nondestructive Testing and Target Identification
Abstract
This grant is concerned with three problems that are related to Air Force needs: 1) The extension of the linear sampling method in target identification from the frequency domain to the time domain, 2) the development of the theory of transmission eigenvalues in nondestructive testing to include the cases of materials involving thin layers and multiple small inhomogeneities, and 3) the use of transmission eigenvalues in nondestructive testing with applications to airplane canopies and related problems. The main accomplishments during the period of this report were: 1. The investigation of the linear sampling method in the time domain for limited aperture data and for objects in a waveguide. 2. The use of asymptotic methods to investigate the transmission eigenvalue problem for inhomogeneous media that contains small penetrable homogeneous inclusions and thin layers and the use of linear sampling methods to detect the delamination of materials. 3. The use of Stekloff eigenvalues in the nondestructive testing of anisotropic, absorbing inhomogneous media.
