International audience; Whenever light is slowed down, for any cause, two different formulas give its momentum. The coexistence of those momenta was the heart of the century-old Abraham-Minkowski dilemma, recently resolved for dielectrics. We demonst

A new kind of time domain simulation for traveling-wave tube (TWT) is presented. The DIMOHA algorithm should be considered as an alternative to current particle-in-cell (PIC) and frequency approaches. To assess its validity, a comparison with a comme

Publikováno v: Chaos, Solitons & Fractals. 145:110810

The E × B electron drift instability, present in many plasma devices, is an important agent in cross-field particle transport. In presence of a resulting low frequency electrostatic wave, the motion of a charged particle becomes chaotic and generate

International audience; The MISTRAL device is designed to produce a linear magnetized plasma column. It has been used a few years ago to study a nonlinear low frequency instability exhibiting an azimuthal number m = 2. By changing the experimental co
