A novel study on subspace migration for imaging of a sound-hard arc
Won-Kwang Park
In this study, the influence of a test vector selection used in subspace migration to reconstruct the shape of a sound-hard arc in a two-dimensional inverse acoustic problem is con…

Topological derivative-based technique for imaging thin inhomogeneities with few incident directions
Won-Kwang Park
Many non-iterative imaging algorithms require a large number of incident directions. Topological derivative-based imaging techniques can alleviate this problem, but lacks a theoret…

Appearance of inaccurate results in the MUSIC algorithm with inappropriate wavenumber
Won-Kwang Park
MUltiple SIgnal Classification (MUSIC) is a well-known non-iterative location detection algorithm for small, perfectly conducting cracks in inverse scattering problems. However, wh…
