Mathematical and experimental validation of the bifocusing method tailored for bistatic measurement
Won-Kwang Park
In this paper, we design a bifocusing-based imaging strategy for the rapid identification of small penetrable dielectric inhomogeneities within a two-dimensional bistatic measureme…

Direct sampling method to retrieve small objects from two-dimensional limited-aperture scattered field data
Won-Kwang Park
In this study, we investigated the application of the direct sampling method (DSM) to identify small dielectric objects in a limited-aperture inverse scattering problem. Unlike pre…

Real-time inversion of two-dimensional Fresnel experimental database using orthogonality sampling method with single and multiple sources: the case of transverse electric polarized waves
Junyong Eom, Sangwoo Kang, Minyeob Lee +1
This paper concerns an application of the orthogonality sampling method (OSM) for a real-time identification of small objects from two-dimensional Fresnel experimental dataset in t…
