Annular electron beam with virtual cathode in a coaxial diode with magnetic insulation
Accumulation of electrons in course of transportation of tubular high-current electron beam in a coaxial diode with magnetic insulation was studied in the situation of counterstream electron motion occurring due to the formation of a virtual cathode. Accumulation of electrons in these flows is accompanied by gradual increase in their relative energy spread and simultaneous decrease in the maxim...

متن کاملNematic between Coaxial Cylinders
The stability of the equilibrium configurations of a nematic liquid crystal confined between two coaxial cylinders is analysed when a radial electric field is applied and the flexoelectric effect is taken into account. The threshold for perturbations depending only on the radius r in the cylindrical coordinate system and strong boundary conditions is studied. A new type of orientational transit...
متن کاملCoaxial Feed Microstrip Patch Antenna
Abstract: In this paper a simple and light weight microstrip patch antenna has been presented. This antena is designed on a FR-4 substrate with dielectric constant of 4.3 and 1.6 mm thickness. The designed antenna is simmulated and anyalized for Body-centric Wireless Communication (BCWC) application, which operates at 5.126 GHz Industrial, Scientific and Medical (ISM) Hyper Local Area Network (...
