7 A ug 2 00 4 Low - frequency instability of circularly polarized microwave - pulsed - field - produced plasmas ∗
نویسنده
چکیده
The plasma produced by a high-power pulsed circularly polarized microwave field which is much weaker than the atomic fields is investigated in the non-relativistic limit. It is shown that the resulting electron distribution function is non-equilibrium and anisotropic. Furthermore, the dispersion equations derived to study and analyze low-frequency ion oscillations. It is shown an instability may grow in the aforementioned system only when the ion density exceeds a critical value. PACS No: 52.40.Db,52.35.Hr E-mail:[email protected] 0

Circularly Polarized Circular Slot Antenna Array Using Sequentially Rotated Feed Network
This paper presents the design, simulation, and measurement of two low-cost broadband circularly polarized (CP) printed antennas: a single element and an array at C band. The proposed single element antenna is excited by an L-shaped strip with a tapered end, located along the circular-slot diagonal line in the back plane. From the array experimental results, the 3 dB axial ratio bandwidth can r...
متن کامل0 Ju l 2 00 4 Weibel instability on weakly relativistic produced plasma by circular polarization microwave electric field ∗
Analyzing the production of weakly relativistic plasma produced by microwave fields with circular polarization the electron distribution function is obtained to be non-equilibrium and anisotropic. Furthermore, it is shown that produced plasma is accelerated on the direction of propagation of microwave electric fields. The electron velocity on this direction strongly depends on electron originat...

In In this paper, two low profile, single fed cavity backed slot antennas providing a circularly polarized (CP) wave are introduced. One of the antennas presents a right-handed CP (RHCP) wave, while the other one offers a left handed CP (LHCP) wave. The proposed antennas consist of a square shaped Substrtae Integrated Waveguide (SIW) cavity incorporatng two couples of radiating slots to radiate...
متن کاملDomain wall propagation due to the synchronization with circularly polarized microwaves
Finding a new control parameter for magnetic domain wall DW motion in magnetic nanostructures is important in general and in particular for the spintronics applications. Here, we show that a circularly polarized magnetic field CPMF at gigahertz frequency microwave can efficiently drive a DW to propagate along a magnetic nanowire. Two motion modes are identified: rigid DW propagation at low freq...
متن کاملThe gravitational field of a light wave
According to the classical Einstein-Maxwell theory of gravity and electromagnetism, a light-wave traveling in empty space-time is accompanied by a gravitational field of the pp-type. Therefore point masses are scattered by a light wave, even if they carry no electric or magnetic charge, or dipole moment. In this paper I present the explicit form of the metric and curvature for both circularly a...
