Formation mechanism of SH guided wave in weld seam
Shear horizontal (SH)-guided wave detection of weld seams is a new type of weld detection technology. To better apply SH-guided waves to weld detection, it is necessary to study the formation mechanism of SH-guided waves and to identify weld structures ...

Surface Acoustic Wave (SAW) Sensors: Physics, Materials, and Applications
Surface acoustic waves (SAWs) are the guided waves that propagate along the top surface of a material with wave vectors orthogonal to the normal direction to the surface.

Numerical simulation of high frequency guided wave testing for anchor bolt defects
Previous research has confirmed that only high-frequency guided waves larger than 1 MHz have the minimum attenuation detection mode for anchor bolt widely used in underground projects.

Defect Detection and Imaging in Composite Structures Using Magnetostrictive Patch Transducers
The use of thin magnetostrictive patches to generate and detect guided waves within the composite samples is investigated for defect detection. This approach has been implemented using SH0 shear horizontal guided waves in both CFRP and GFRP plates.

Guided Modes in Negative Refractive Index Waveguides [PDF]
We study linear guided waves propagating in a slab waveguide made of a negative-refraction- index material, the so-called left-handed waveguide. We reveal that the guided waves in left-handed waveguides possess a number of peculiar properties, such as ...

A Metacoupler for Converting Propagating Waves to Guided Waves in Wire Waveguides
Propagating electromagnetic waves in free space cannot directly couple to guided waves in waveguides due to momentum mismatch. Here, we propose a method to design a metacoupler that can convert propagating waves into guided waves along wire waveguides in

Transversely periodic solitary-wave solutions of the Boussinesq equations (which govern wave propagation in a weakly dispersive, weakly nonlinear physical system) are determined. The solutions for negative dispersion (e.g., gravity waves) are singular and therefore physically unacceptable. The solutions for positive dispersion (e.g., capillary waves or

Propagating transverse waves in soft X-ray coronal jets [PDF]
Aims. The theoretical model for magnetohydrodynamic (MHD) modes guided by a field-aligned plasma cylinder with a steady flow is adapted to interpret transverse waves observed in solar coronal hot jets, discovered with Hinode/XRT in terms of fast ...

Universal diagrams for te waves guided by thin films bounded by saturable nonlinear media [PDF]
It is shown that universal V-b diagrams provide a powerful tool when analyzing the stationary waveguiding properties of the TE waves guided by a thin film bounded by a saturable nonlinear substrate or cladding.

Elastic Properties Measurement Using Guided Acoustic Waves
Nondestructive evaluation of elastic properties plays a critical role in condition monitoring of thin structures such as sheets, plates or tubes. Recent research has shown that elastic properties of such structures can be determined with remarkable ...
