Asymptotic expansions of Stekloff eigenvalues for perturbations of inhomogeneous media
Samuel Cogar
Eigenvalues arising in scattering theory have been envisioned as a potential source of target signatures in nondestructive testing of materials, whereby perturbations of the eigenv…
Existence and stability of electromagnetic Stekloff eigenvalues with a trace class modification
Samuel Cogar
A recent area of interest is the development and study of eigenvalue problems arising in scattering theory that may provide potential target signatures for use in nondestructive te…
Modified electromagnetic transmission eigenvalues in inverse scattering theory
Samuel Cogar, Peter Monk
A recent problem of interest in inverse problems has been the study of eigenvalue problems arising from scattering theory and their potential use as target signatures in nondestruc…
Eigenvalue problems in inverse electromagnetic scattering theory
Samuel Cogar, David Colton, Peter Monk
The inverse electromagnetic scattering problem for anisotropic media in general does not have a unique solution. A possible approach to this problem is through the use of appropria…
