By fixing two fundamental constants from quantum mechanics, the Planck constant $h$ and the elementary charge $e$, the revised Syst\`eme International (SI) of units endorses explicitly quantum mechanics. This evolution also highlights the importance

This paper outlines a practical realization of the farad in the revised SI at LNE. To improve the traceability of the unit of capacitance in the SI with a target relative standard uncertainty of one part in 108, a new Thompson-Lampard calculable capa

Sea state can influence the turbulent air–sea exchanges, especially the momentum flux, by modifying the sea-surface roughness. The high-resolution non-hydrostatic convection-permitting model MESO-NH is used here to investigate the impact of a more

To improve the traceability of the unit of capacitance in the SI with a relative standard uncertainty of about one part in 108, a new Thompson-Lampard calculable capacitor is currently developed at LNE. This paper presents the progress on the alignme

Within the framework of the Supplementary Comparison EURAMET.EM-S31, the capacitance derived from the quantized Hall resistance at either ac or dc as well as the 10:1 capacitance ratio was intercompared. In addition, the frequency dependence of two t

This paper describes a comparison of the frequency dependence of two capacitance ratios using newly developed impedance bridges from LNE and PTB. LNE designed an IVD based setup, whereas PTB used its Josephson impedance bridge for the measurements. R
