Leaky waves are an important class of waves, particularly for guiding waves along structures embedded within another medium; a mismatch in wavespeeds often leads to leakage of energy from the waveguide, or interface, into the medium, which consequently attenuates the guided wave. The accurate and efficient identification of theoretical solutions for leaky waves is a key requirement for the choices of modes and frequencies required for non-destructive evaluation inspection techniques. We choose…

Calculating the full leaky Lamb wave spectrum with exact fluid interaction.

The full phase velocity dispersion diagram and attenuation curves are presented and are shown to be in excellent agreement with solutions of the characteristic equation as well as computations made with a perturbation method.

Modeling guided elastic waves in generally anisotropic media using a spectral collocation method.

In this paper a spectral collocation method is successfully used to handle the more complicated and realistic waveguide problems that are required in non-destructive evaluation; many pitfalls and limitations found in root-finding routines based on the partial wave method are overcome by using this approach.

Modeling of wave dispersion along cylindrical structures using the spectral method.

Algorithm and code are presented that solve dispersion equations for cylindrically layered media consisting of an arbitrary number of elastic and fluid layers. The algorithm is based on the spectral

Guided waves' dispersion curves in anisotropic viscoelastic single- and multi-layered media

Guided waves propagating in lossy media are encountered in many problems across different areas of physics such as electromagnetism, elasticity and solid-state physics. They also constitute essential

Ultrasonic leaky guided waves in fluid-coupled generic waveguides: hybrid finite-boundary element dispersion analysis and experimental validation

A numerical procedure is presented for the computation of dispersive parameters in elastic mechanical waveguides of generic cross-section immersed in non-viscous fluids. The method uses a

Acoustic radiation from submerged plates. I. Influence of leaky wave poles

Leaky wave poles are defined as those singularities of the acoustic admittance of a fluid‐loaded infinite plate that are located on the bottom Riemann sheet of the complex wavenumber plane and can
