Chaos in Si MMIC Oscillators [PDF]

open access: yes29th European Microwave Conference, 1999, 1999
This paper analyzes the dynamics of two Si circuits in miliimetric band for which chaotic responses had been experimentally observed. The aim has been to determine, in each case, the particular phenomena leading to the chaotic response, in order to avoid this behavior in future realizations of these circuits.

Convective Organization in African Easterly Waves Observed During the NAMMA and CPEX‐CV Field Campaigns

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Fundamental questions remain about where and when convection will occur within African easterly waves. In this study, we aim to better understand the dynamical processes that govern moist convective organization at the meso‐alpha scale in tropical easterly waves using NASA airborne field campaigns and satellite observations.
