Physical Review A, 1993
As is well known, the stimulated Raman scattering (SRS) in nonlinear optical fibers precludes the existence of stable solitary waves both of bright and dark soliton types. For bright solitons, the SRS effect can affect the temporal evolution even for pulses as wide as a few picoseconds causing a continuous frequency down shift1,2.

Physical Review Letters, 1980
It is found that, by means of numerical simulations, an ion acoustic instability (v/sub d/ < v/sub te/) results in the formation of double layers in a sufficiently long system. Anomalous resistivity generated by the ion acoustic instability causes the buildup of a dc potential which in turn accelerates electrons further to enhance the original ...

Double‐layered lateral meniscus
Knee Surgery, Sports Traumatology, Arthroscopy, 2011AbstractA case of double‐layered lateral meniscus in which an accessory proximal hemimeniscus was overlying the body and posterior horn of the lateral meniscus is here reported. The accessory hemimeniscus lays marginal and parallel to the normal lateral meniscus with its periphery dissociated from the capsule and was significantly thinner and more ...

The characteristics of weak double layers with potential steps approximately equal to five are investigated in a triple plasma device and compared with a kinetic model. The double layers considered here differ from those previously investigated in two significant ways: (1) the double layers are much weaker; and (2) trapped ions play a much less ...

This paper examines the potential for dual-layer actuators to achieve radiation efficiencies independent of the backing structure. It presents a simple center-of-mass representation for the device, and uses it to describe the kinematics of the dual layer actuator system with the purpose of identifying broad guidelines regarding thickness and frequency ...

The Physics of Fluids, 1983
Based on realistic velocity distributions, analytic solutions of monotonic double layers which essentially agree with observations are obtained. A universal constant is found which relates potential drop, free ion energy, and trapped ion temperature in a simple manner.

Abstract Using a triple-plasma device, moving double layers have been produced by abruptly increasing the plasma density in the region of the double layers. Propagation velocities up to 3.5 c s have been achieved with their velocity scaling as ν ∼ (2e × δϕ T e ) 1 2 c S .

Strong electric potential double layers (eφ/Te≳10) are produced in the University of Iowa’s triple plasma device. The electron beam which results from acceleration by the double layer maintains its identity with little heating until it reaches the end of the chamber.
