The Stekloff eigenvalue problem has been a recent problem of interest due to its potential use in the nondestructive testing of materials, but it suffers from two shortcomings that are common among...

Eigenvalues arising in scattering theory have been envisioned as a potential source of target signatures in nondestructive testing of materials, whereby perturbations of the eigenvalues computed for a penetrable medium would be used to infer changes

We introduce a new eigenvalue problem arising from electromagnetic scattering which may potentially be used as a target signature in nondestructive testing of materials. After establishing some basic properties of this eigenvalue problem, we show tha

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 nondestructive testing of materials. Towards this pursuit we introduce a new eig

Radial Basis Function (RBF) methods are important tools for scattered data interpolation and for the solution of PDEs in complexly shaped domains. Several approaches for the evaluation of RBF methods are known. To date, the most noteworthy methods ar

We consider the scattering of an acoustic plane wave by an inhomogeneous medium of compact support. Our aim is to introduce a new class of target signatures that can be used to detect changes in the material properties of the scattering object from a
