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 ...

Leaky wave characterisation using spectral methods
The Journal of the Acoustical Society of America, 2022 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.

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 ...
