Saturation of the Farley-buneman Instability via Nonlinear Electron Eb Drifts
The Farley-Buneman instability is a collisional two-stream instability observed in the E-region ionosphere at altitudes in the range 90-120km. While linear theory predicts the dominant wavelengths, it cannot fully describe the behavior of this nonlinearly saturated instability as observed by radar and rocket measurements. This paper explores the nonlinear behavior of this phenomenon and the res...
متن کاملCollisional, magnetic, and nonlinear skin effect in radio-frequency plasmas
The penetration of radio-frequency energy into cylindrical devices is relevant to the production of uniform plasmas for etching and deposition processes in the production of semiconductor circuits. The so-called ‘‘anomalous skin effect’’ has been invoked to explain irregularities not predicted by classical electromagnetic theory. These expectations are summarized for the collisionality regimes ...
متن کاملLow-rank approximation in the numerical modeling of the Farley-Buneman instability in ionospheric plasma
We consider the numerical modeling of the Farley-Buneman instability development in the earth’s ionosphere plasma. The ion behavior is governed by the kinetic Landau equation in the four-dimensional phase space, and since the finite difference discretization on a tensor product grid is used, this equation becomes the most computationally challenging part of the scheme. To relax the complexity a...
متن کاملLow Power and Low Latency Phase-Frequency Detector in Quantum-Dot Cellular Automata Nanotechnology
Nowadays, one of the most important blocks in telecommunication circuits is the frequency synthesizer and the frequency multipliers. Phase-frequency detectors are the inseparable parts of these circuits. In this paper, it has been attempted to design two new structures for phase-frequency detectors in QCA nanotechnology. The proposed structures have the capability of detecting the phase ...
متن کاملSaturation of the Farley-Buneman instability via three-mode coupling
[1] Characteristics of type-1 radar echoes obtained from the E region ionosphere have yet to be conclusively explained. The dynamical properties of the saturated state of the FarleyBuneman instability are widely thought responsible for these type-1 echoes. In this paper we present a different perspective and new details on a previously proposed three-wave coupling mechanism (Otani and Oppenheim...
