Predicting the coupling of HPEM waveform with a power amplifier in perforated conductive enclosure using FDDM/VF

IET Science, Measurement &Technology, Volume 18, Issue 8, Page 429-442, October 2024.
The impact of high‐power electromagnetic on the power amplifier inside the conductive enclosure has been investigated. By using the finite difference delay modelling numerical method as a stable method followed by the vector fitting method, the electromagnetic problem has become a circuit problem, which allows examining the response of the power ...

Toward a common methodological framework for the sampling, extraction, and isotopic analysis of water in the Critical Zone to study vegetation water use

WIREs Water, Volume 11, Issue 4, July/August 2024.
As isotopic analyses for the estimation of vegetation water use becomes more widespread, we need a common framework for the site description, sampling design, sample collection, transport and storage of samples, water extraction, in the laboratory or in situ, and analysis of the isotopic composition.
