Excitation and propagation of torsional T(0,1) mode for guided wave testing of pipeline integrity
Measurement, 2019Guided wave testing is one of non-destructive testing techniques for pipeline inspection using low-frequency ultrasonic waves. Guided wave testing uses a set of equally placed piezoelectric transducers around a pipe, and the number of transducers in the ...

Detection and sizing of disbond in multilayer bonded structure using modally selective guided wave
Structural Health Monitoring, 2019Bonded structures are frequently adopted in structural connections and are highly prone to degradation or decrease of interfacial strength due to adhesive aging, poor quality of surface preparation, as well as the exposure to harsh environment and ...

Acoustoelastic guided wave propagation in axial stressed arbitrary cross-section
Smart materials and structures (Print), 2019This paper investigates the effect of axial stress on acoustoelastic guided wave propagation in arbitrary cross-section. Many researchers have investigated the effect of stress on guided wave propagation in arbitrary cross-section. However, the effect of

Surface waves and guided waves
1956Although surface waves and guided waves may exist under a wide variety of conditions our main concern will be those generated in the earth by earthquakes or explosions. These waves are of interest to seismologists not only because they form the most prominent features of seismograms but also for their usefulness in determining the structure of the ...

Wave Harmonics and Guided Waves
2014Solutions of the homogeneous Helmholtz equation are referred to as wave harmonics. In this chapter, we will discuss the solution of this equation in rectangular, cylindrical and spherical coordinate systems. They are respectively called plane waves, cylindrical waves and spherical waves.

Nonlinear Guided Wave Phenomena
Topical Meeting on Optical Bistability (OB3), 1985Integrated optics waveguides are ideal media for nonlinear optical interactions because high power densities can be maintained over centimeter propagation distances. Recent work in our laboratory, as well as that of other workers in the field will be reviewed. Liquid crystal media placed on top of thin films provide simple nonlinear waveguides in which

Journal of Applied Physics, 1948
The paper is devoted to a discussion of the properties of electromagnetic waves propagating with a velocity W <c. Boundary conditions are obtained for structures with very narrow slots, either closed or open, and a general method of solution of the wave equations is discussed.
