Fast magnetoacoustic waves in curved coronal loops. I, Trapped and leaky modes [PDF]
, 2006 A study of vertically polarised fast magnetoacoustic waves in a curved coronal loop is presented. The loop is modeled as a semi-circular magnetic slab in the zero plasma-β limit. The governing equations for linear waves are derived. We show that the wave

Visualization of leaky waves on planar transmission lines [PDF]
, 2004 This paper presents a visualization of leaky waves excited by delta-gap sources on planar transmission lines, namely the 2nd surface and space leaky modes on the slotline, and the dominant and surface leaky modes on the conductor-backed slotline.

Edge and Notch Detection in a Plate Using Time Reversal Process of Leaky Lamb Waves
Applied Sciences, 2021 Leaky Lamb waves are proven effective to carry out nondestructive testing especially on parallel and immersed plates. To detect and localize defects in such a set, this work associates for the first time the topological energy method and leaky Lamb waves.

New Space Leaky Wave Spectrum Components on the Slotline [PDF]
, 2000 Surface and space leakage of power deteriorates the operation of circuits. On the other hand space leaky waves enable the design of specific radiators. In this paper we therefore investigate the potential of the slotline to radiate into space. We confirm

Evolution of New Real and Complex Improper Solutions of the Slotline Dispersion Equation [PDF]
, 1997 An attempt is made in this paper to reach a better understanding of the behaviour of open uniplanar circuits, particularly the slotline. A new second leaky wave has been revealed in addition to the dominant bound and leaky waves known up to now.

Elastic Wave Eigenmode Solver for Acoustic Waveguides [PDF]
, 2017 A numerical solver for the elastic wave eigenmodes in acoustic waveguides of inhomogeneous cross-section is presented. Operating under the assumptions of linear, isotropic materials, it utilizes a finite-difference method on a staggered grid to solve for

Leakage Effects of Dominant and Higher Order Modes on Slotline [PDF]
, 1996 The properties of the slotline when the dominant bound or leaky wave propagates, together with the behaviour of new higher order modes are investigated. The frequency range in which the slotline transmits the bound wave only is determined and the closed ...
