Pseudo‐Waveform‐Selective Metasurfaces and their Limited Performance

open access: yes, 2021
In recent years, metasurfaces composed of lumped circuit components, including nonlinear Schottky diodes, have been reported to be capable of sensing particular electromagnetic waves even at the same frequency depending on their waveforms, or more ...

Electrofishing eel, salmon and trout: impact of waveform and frequency on capture-per-unit-effort and spinal damage

open access: yesKnowledge and Management of Aquatic Ecosystems, 2020
Performing fish survey protocols with different electrofishing equipment and settings can lead to difficulties in comparing the data obtained. In this study, we captured two fish taxa (i.e. the European eel and salmonids: Atlantic salmon and brown trout)

Reflection intensity waveform inversion

open access: yes, 2020
Traditional iteration-based full-waveform inversion (FWI) methods encounter serious challenges if the initial velocity model is far from the true model or if the observed data are lacking low-frequency content.

Slope Estimation from ICESat/GLAS

open access: yesRemote Sensing, 2014
We present a novel technique to infer ground slope angle from waveform LiDAR, known as the independent slope method (ISM). The technique is applied to large footprint waveforms (\(\sim\) mean diameter) from the Ice, Cloud and Land Elevation Satellite ...
