In this work, we provide a proof of the so-called Karp's theorem in a different approach. We use the unique continuation principle together with the monotonicity of eigenvalues for the negative Laplace operator. This method is new and would be a... see more

This paper deals with the problem of the electromagnetic linear inverse scattering from magnetic anomaliesburied in a lossy half space, for a scalar and two dimensional case. First, the formulation of the exact model ofthe electromagnetic scattering is gi... see more

This paper shows new proof of non-uniqueness of the solution for the retrieving of a compact-supported functionstarting from a finite number of samples of its spectrum. As will be shown, this is relevant for linear inversescattering problems, that in many... see more

We address the inverse light-scattering problem for particles described by a several-parameters model, when experimental data are given as an angle-resolved light-scattering pattern (LSP). This problem is reformulated as an optimization (nonlinear regress... see more

The aim of this paper is to investigate the role of multiple views and multiple frequencies in linear inverse scattering problems. The study was performed assuming the Fresnel-zone approximation on the scattering operator. Due to the crucial role played b... see more

This paper presents a computational technique for mono-static and bi-static scattering from underwater objects of different shape such as submarines. The scatter has been computed using finite element time domain (FETD) method, based on the superposition ... see more

The magnetic transport properties -- magnetoresistive (MR) effects of MnNi/Co/Ag(Cu)/\break Py pinned spin valve structures (SVs) prepared by rf sputtering method and annealed at Ta=100T_{a} = 100°C - 500°C for 30 minutes in high vacuum (~10-5\sim 10^{ - ... see more

In this article, we consider the one-dimensional inverse source problem for Helmholtz equation with attenuation (damping) factor in a one layer medium. We establish a stability by using multiple frequencies at the two end points of the domain which contai... see more

In this paper, we are investigating the one dimensional inverse source problem for Helmholtz equation where the source function is compactly supported in our domain. We show that increasing stability possible using multi-frequency wave at the two endpoint... see more
