Journal ArticleDOI
Identification and rational L 2 approximation: a gradient algorithm
TL;DR: To the knowledge, the algorithm described in this paper is the first that ensures convergence to a local minimum of the criterion in the case of scalar systems.
Journal ArticleDOI

TL;DR: In this article, an optimization procedure for microwave filters and multiplexers is proposed, which is initialized by a classical filter synthesis based on a segmented electromagnetic synthesis that provides the basic dimensions of the structure.
Journal ArticleDOI
Recovery of pointwise sources or small inclusions in 2D domains and rational approximation
TL;DR: In this article, the inverse problems of locating pointwise or small size conductivity defaults in a plane domain, from overdetermined boundary measurements of solutions to the Laplace equation, are considered.
Journal ArticleDOI
How can the meromorphic approximation help to solve some 2D inverse problems for the Laplacian
TL;DR: In this paper, a family of inverse problems for the 2D Laplacian related to non-destructive testing is introduced. But the complexity of the inverse problem is not the same as that of approximation theory in the complex domain.
Journal ArticleDOI
Fast inversion of magnetic field maps of unidirectional planar geological magnetization
TL;DR: In this article, a fast inversion technique based on classic methods developed for the Fourier domain was proposed to retrieve planar unidirectional magnetization distributions from magnetic field maps.
