Analysis on the change characteristics of waveform during the transmission of continuous wave mud pulse signal

open access: yesAlexandria Engineering Journal, 2023
Continuous wave mud pulse transmission is the most widely used information transmission technology in measurement while drilling (MWD). The increase in transmission distance will cause the signal attenuation and deformation during transmission, the ...

Design Formulae of Wave Transmission due to Oblique Waves at Low Crested Structures

open access: yesJurnal Teknik Sipil, 2011
Low crested structures, including submerged breakwaters, may be provided to protect the beach from wave attack. These structures can be built parallel to the shoreline and the crest is set up at or below water levels. It function is to protect the beach

A Probabilistic Design Framework for Semi-Submerged Curtain Wall Breakwaters

open access: yesInfrastructures
Semi-submerged curtain breakwaters are increasingly favored to protect marinas and other microtidal basins, yet they are still almost exclusively designed with deterministic wave transmission equations.

Periodic Arrays of Film-Coupled Cubic Nanoantennas as Tunable Plasmonic Metasurfaces

open access: yesPhotonics, 2015
We show theoretically that a two-dimensional periodic array of metallic nanocubes in close proximity to a metallic film acts as a metasurface with tunable absorbance. The presence of a metallic film underneath the array of plasmonic nanocubes leads to an

Numerical modeling of bamboo fences with various infill porosities deployed for mangrove restoration

open access: yesFrontiers in Marine Science
As part of mangrove restoration initiatives eco-friendly fence has been implemented in eroded coastal areas in recent years. These fences provide the capacity to mitigate incoming wave energy and facilitate sediment deposition, thereby promoting the ...
