We propose a new strategy for narrow band, active array imaging of weak localized
scatterers when only the intensities are recorded and measured at the array. We consider a …

Scattering of a time-harmonic plane elastic wave by a rigid obstacle embedded in an
isotropic homogeneous elastic medium has wide applications in science and engineering …

This paper deals with an inverse scattering problem in an acoustic waveguide. The data
consist of time domain signals given by sources and receivers located on the boundary of …

De nombreuses structures utilisées industriellement peuvent être considérées comme des
guides d'ondes, comme les plaques, les tuyaux ou encore le rails. La maintenance de ces …

We present a method for imaging the polarization vector of an electric dipole distribution in a
homogeneous medium from measurements of the electric field made at a passive array. We …
