Particle Acceleration in a Folded Current Sheet

Two-dimensional particle simulations of a relativistic Harris current sheet of pair (e ±) plasmas have demonstrated that the system is unstable to the rela-tivistic drift kink instability and that a new kind of acceleration process takes place in the deformed current sheet. This process contributes to the generation of non-thermal particles and contributes to the fast magnetic dissipation in th...

A periodic folded piezoelectric beam for efficient vibration energy harvesting

Periodic piezoelectric beams have been used for broadband vibration energy harvesting in recent years. In this paper, a periodic folded piezoelectric beam (PFPB) is introduced. The PFPB has special features that distinguish it from other periodic piezoelectric beams. The Adomian decomposition method (ADM) is used to calculate the first two band gaps andtwelve natural frequencies of the PF...

Twt Amplifier Using a Ferroelectric Cathode for Electron Beam Generation

We report first experiments on high-power traveling wave amplifiers using an electron beam generated with a ferroelectric cathode. The electron beam, which is driven by a ferrite core transformer-pulse line system, has energy of 440 keV and a beam current of 40-50 Amperes. The beam pulse duration is about 250 ns and the system is operated at 0.07 Hz. The beam is generated from a command switche...

Design of Multiple Beam Forming Antenna System Using Substrate Integrated Folded Waveguide (SIFW) Technology

This paper introduces a novel structure of 4×4 multiple beam forming antenna system using substrate integrated folded waveguide technology. For high speed wireless communication it is necessary to minimize the interferences and multipath fading. Multiple beam forming antenna system is a good solution to these problems. The substrate integrated folded waveguide (SIFW) technology reduces the widt...

Folded Sheet Versus Transparent Sheet Models for Human Symmetry Judgments

As a contribution to the mysteries of human symmetry perception, reaction time data were collected on the detection of symmetry or repetition violations, in the context of short term visual memory studies. The histograms for reaction time distributions are rather narrow in the case of symmetry judgments. Their analysis was performed in terms of a simple kinetic model of a mental process in two ...
