Sideband mode competition in a gyrotron oscillator
Physical Review Letters, 1992We report the first observation of sideband mode competition in a gyrotron with an overmoded open waveguide resonator. Experiments were conducted in a gyrotron operating in the ${\mathrm{TE}}_{16,2}$ mode at 146 GHz. Up to 600 kW of power was generated in 3-\ensuremath{\mu}s pulses at 80 kV beam voltage and up to 40 A beam current.

P-Mode Oscillations of α Cen A
Astrophysics and Space Science, 2003Models of α Cen A & B have been computed using the masses determined by Pourbaix et al. (2002) and the data derived from the spectroscopic analysis of Neuforge and Magain (1997). The seismological data obtained by Bouchy and Carrier (2001, 2002) do help improve our knowledge of the evolutionary status of the system.

Electronegative nonlinear oscillating modes in plasmas
Communications in Nonlinear Science and Numerical Simulation, 2018Abstract The emergence of nonlinear modulated waves is addressed in an unmagnetized electronegative plasma made of Boltzmann electrons, Boltzmann negative ions and cold mobile positive ions. The reductive perturbation method is used to reduce the dynamics of the whole system to a cubic nonlinear Schrodinger equation, whose the nonlinear and ...

Existence of Proper Modes of Helicon Oscillations
Journal of Mathematical Physics, 1965In this paper it is shown that the class of electromagnetic problems for which the operator i(∂/∂t) (where t denotes time) is self-adjoint extends beyond problems involving only insulators and perfect conductors. The class includes problems in which the perfect conductor is generalized to a medium with antisymmetric resistivity tensor.
