A Lamb wave-based, subwavelength imaging algorithm is developed for damage imaging in
a metallic plate based on a decomposition of the time-reversal operator method together …

Guided wave tomography is a promising tool to accurately determine the remaining wall
thicknesses of corrosion damages, which are among the major concerns for many …

The iterative Born approximation (IBA) is a well-known method for describing waves
scattered by semitransparent objects. In this letter, we present a novel nonlinear inverse …

This paper is concerned with a nonlinear imaging problem, which aims to reconstruct a
locally perturbed, perfectly reflecting, infinite plane from intensity-only (or phaseless) far-field …

The problem of locating point-like targets beyond the classical resolution limit is revisited.
Although time-reversal MUltiple SIgnal Classification (MUSIC) is known for its super …

In this paper, according to the disperse curve of composite laminates in a low frequency
domain, a quantitative relation between anisotropic wavefront and propagation direction is …

Although classical imaging is limited by the Rayleigh criterion, it has been demonstrated that
subwavelength imaging of two point-like scatterers can be achieved with probing sensors …

In diagnostic ultrasound imaging, the image reconstruction quality is crucial for reliable
diagnosis. Applying reconstruction algorithms based on the acoustic wave equation, the …

Experimental results are presented for the focusing capability of an active phase conjugating
lens for a single and a dipole source pair and these are compared with predictions. In …

The imaging properties of a phase conjugating lens operating in the far field zone of the
imaged source and augmented with scatterers positioned in the source near field region are …
