Plane Wave Imaging through Interfaces [PDF]
Sensors, 2021 Plane Wave Imaging (PWI) has been recently proposed for fast ultrasound inspections in the Non-Destructive-Testing (NDT) field. By using a single (or a reduced number) of plane wave emissions and parallel beamforming in reception, frame rates of hundreds

Lukash plane waves, revisited [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 The Lukash metric is a homogeneous gravitational wave which at late times approximates the behaviour of a generic class of spatially homogenous cosmological models with monotonically decreasing energy density. The transcription from Brinkmann to Baldwin-Jeffery-Rosen (BJR) to Bianchi coordinates is presented and the relation to a Sturm-Liouville ...

Propagation of waves in an incompressible rotating transversely isotropic nonlocal elastic solid
Vietnam Journal of Mechanics, 2021 In this paper, the nonlocal elasticity theory is applied to study the propagation of plane wave and Rayleigh-type surface wave in an incompressible, rotating and transversely isotropic material.

Multi Spherical Wave Imaging Method Based on Ultrasonic Array
Sensors, 2022 The imaging range of traditional plane wave imaging is usually limited by the directivity of the plane wave. In this paper, a multi spherical wave imaging method based on an ultrasonic array is proposed, which radiates both compression and shear waves in

Interpolated Plane Wave Imaging: IPWI
e-Journal of Nondestructive Testing, 2023 This paper offers a solution to the problems caused by sub-Nyquist spatial sampling in ultrasound image generation, which can result in aliasing and grating lobes in Full Matrix Capture (FMC) and Plane Wave Imaging (PWI). Neglecting the spatial sampling

Nuclear Physics B, 2003 Motivated by the search for potentially exactly solvable time-dependent string backgrounds, we determine all homogeneous plane wave (HPW) metrics in any dimension and find one family of HPWs with geodesically complete metrics and another with metrics containing null singularities.

AN OPERATOR METHOD FOR THE PROBLEM OF PLANE WAVE DIFFRACTION BY INFINITELY THIN, PERFECTLY CONDUCTING HALF-PLANE AND TWO DISKS [PDF]
Radio Physics and Radio Astronomy, 2022 Subject and Purpose. Considered in the paper is diffraction of a plane wave by a structure involving a half-plane and two disks. The disks and the half-plane, lying within parallel planes, are assumed to be infinitely thin and perfectly conducting.

Plane Wave Reverse Time Image for Nondestructive Tests
IEEE Access, 2023 Reverse time migration (RTM) has been a popular method in industry duo to its ability of imaging complex subsurface and no dip restriction. However, RTM based on full matric capture (FMC) data is limited by the time cost of the calculation and cannot be ...
