Nonlinear propagation of leaky TE-polarized electromagnetic waves in a metamaterial Goubau line

open access: yesMathematical Modelling and Analysis, 2021
Propagation of leaky TE-polarized electromagnetic waves in the Goubau line (a perfectly conducting cylinder covered by a concentric dielectric layer) filled with nonlinear metamaterial medium is studied.

The Electromagnetic Field for a PEC Wedge Over a Grounded Dielectric Slab: 2. Diffraction, Modal Field, Surface Waves, and Leaky Waves [PDF]

open access: yes, 2017
Together with Part 1, Part 2 describes the theory, the validation, and the application of the generalized Wiener-Hopf technique (GWHT) to complex scattering problems constituted of wedges and layers that may interact at near field.

Visualization of leaky waves on planar transmission lines [PDF]

open access: yes, 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

open access: yesApplied 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.

Leaky-Wave Structures and Techniques for Integrated Front-End Antenna Systems

open access: yesIEEE Journal of Microwaves, 2023
Leaky-wave antenna (LWA), as a special kind of waveguiding structure simultaneously characterized by both the guidance and radiation of electromagnetic waves along it, has received much attention and has been in the spotlight of both academia and ...

Dispersion of Rayleigh Waves in a Microstructural Couple Stress Substrate Loaded with Liquid Layer Under the Effects of Gravity

open access: yesArchives of Acoustics, 2018
Bone loss is one of the serious health issues in bedridden patients or young generation due to lack of physical activities. Mechanical forces are exerted on the bones through ground reaction forces, liquid loadings and by other contraction activities of ...

Leaky-wave metasurfaces for integrated photonics

open access: yesNature Nanotechnology, 2023
Metasurfaces have been rapidly advancing our command over the many degrees of freedom of light within compact, lightweight devices. However, so far, they have mostly been limited to manipulating light in free space. Grating couplers provide the opportunity of bridging far-field optical radiation and in-plane guided waves, and thus have become ...

Surface True and Leaky Waves in Subsonic and Supersonic Regions. Explicit Solution of a Simple Model [PDF]

open access: yes, 2010
A simple model of a surface of a 2D continuum is shown to exhibit subsonic and supersonic surface resonances (leaky waves, pseudosurface waves), i.e. finite-lived excitations, along with usual surface waves (true subsonic surface waves).
