Determination of the unknown support of thin penetrable inclusions within a half-space from multi-frequency response matrix
Won-Kwang Park, Dominique Lesselier
Thin, penetrable electromagnetic inclusions buried within a half space are retrieved from Multi-Static Response (MSR) matrix data collected above this half space at several frequen…
Asymptotic properties of MUSIC-type imaging in two-dimensional inverse scattering from thin electromagnetic inclusions
Won-Kwang Park
The main purpose of this paper is to study the structure of the well-known non-iterative MUltiple SIgnal Classification (MUSIC) algorithm for identifying the shape of extended elec…
Multi-frequency based location search algorithm of small electromagnetic inhomogeneities embedded in two-layered medium
Won-Kwang Park, Taehoon Park
In this paper, we consider a problem for finding the locations of electromagnetic inhomogeneities completely embedded in homogeneous two layered medium. For this purpose, we presen…
Fast shape reconstruction of perfectly conducting cracks by using a multi-frequency topological derivative strategy
Won-Kwang Park
This paper concerns a fast, one-step iterative technique of imaging extended perfectly conducting cracks with Dirichlet boundary condition. In order to reconstruct the shape of cra…
Analysis of a multi-frequency electromagnetic imaging functional for thin, crack-like electromagnetic inclusions
Won-Kwang Park
Recently, a non-iterative multi-frequency subspace migration imaging algorithm was developed based on an asymptotic expansion formula for thin, curve-like electromagnetic inclusion…
Structure analysis of single- and multi-frequency subspace migrations in inverse scattering problems
Young Deuk Jo, Young Mi Kwon, Joo Young Huh +1
In this literature, we carefully investigate the structure of single- and multi-frequency imaging functions, that are usually employed in inverse scattering problems. Based on patt…
Multi-frequency topological derivative for approximate shape acquisition of curve-like thin electromagnetic inhomogeneities
Won-Kwang Park
In this paper, we investigate a non-iterative imaging algorithm based on the topological derivative in order to retrieve the shape of penetrable electromagnetic inclusions when the…
Multi-frequency imaging of perfectly conducting cracks via boundary measurements
Won-Kwang Park, Dominique Lesselier
Imaging of perfectly conducting crack(s) in a 2-D homogeneous medium using boundary data is studied. Based on the singular structure of the Multi-Static Response (MSR) matrix whose…
