Computational imaging of micro-structured systemsas a grid-like set of a finite number of circular cylindricaldielectric rods is considered. How to achieve meaningful localization,resolution-enhanced or, even, super-resolved, vs. thewavelength(s) of operation if defects or radiators are to be foundwithin is discussed here. That is, the set can be s...
Flaw characterization in eddy current testing usually requires to solve a nonlinear inverse problem. Due to high computational cost, Markov Chain Monte Carlo (MCMC) methods are hardly employed since often needing many forward evaluations. However, they have good potential in dealing with complicated forward models and they do not reduce to only pro...

Ce-doped SiO x N y films are deposited by magnetron reactive sputtering from a CeO 2 target under nitrogen reactive gas atmosphere. Visible photoluminescence measurements regarding the nitrogen gas flow reveal a large emission band centered at 450 nm for a sample deposited under a 2 sccm flow. A special attention is paid to the origin of such an em...
In this paper, we propose to replace the usual dedicated electronic power supplies of superconducting coil, which are in most cases a huge volume and/or a low energy yield, by a 100 cm² single proton exchange membrane fuel cell (PEMFC). Indeed, fuel cells are electrochemical converters which can be considered as DC low voltage electrical source. Pr...
A family of difference integral equations, consisting of difference Lippmann-Schwinger integral equation (D-LSIE)and difference new integral equation (D-NIE), is proposed to solve the electromagnetic inverse scattering problems(ISPs) with inhomogeneous background medium bounded in a finite domain. Without resorting to Green’s function forinhomogene...

The magnetostatic vector fields in terms of harmonic scalar potentials scattered by near–surface air inclusion ofarbitrary shape, embedded in a conductive ferromagnetic medium, are investigated. The hollow inclusion is illuminatedby a current–carrying coil, which serves as the primary field. The do-main of interest is separated into homogeneoussubd...
