2023 17th European Conference on Antennas and Propagation (EuCAP), 2023 AbstractLeaky waves are complex eigenmodes compatible with radiation in terms of their momentum, which can be supported by open waveguiding structures and can be effective at modeling radiative phenomena from such systems. Here, a “flatland” analog of leaky‐wave radiation is introduced to describe a novel mechanism for in‐plane radiation leakage that ...

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.

Directive Emission from Defect-Free Dodecagonal Photonic Quasicrystals: A Leaky-Wave Characterization [PDF]
, 2009 In this paper, we study the radiation from embedded sources in two-dimensional finite-size "photonic-quasicrystal" (PQC) slabs made of dielectric rods arranged according to a 12-fold symmetric aperiodic tiling.

Flow estimation in a steel pipe using guided waves [PDF]
, 2016 In this investigation, a flow rate estimation guided wave based scheme in pipes is proposed. The effect of the fluid over the propagation of longitudinal waves has been experimentally studied by using several laminar flows of water transported by a ...

Leaky-wave metasurfaces for integrated photonics
Nature 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 ...
