Programmable Device Circuits and Systems

Abstract

First of all we have taken into consideration of different type of parameters such as electric field, current, electrostatic field etc. We have proposed to calculate collision frequency and different type of conductivity such as hall conductivity, Pederson conductivity and cowling conductivity, in narrow belt (ribbon) of equatorial region where heavy current flow occurs. The current density flows between the ionosphere and surface has been discussed. It generates electron ion concentration dependent on current density and conductivity gradient. I have tried to correlate electric field and electrostatic field. I have also focused on magnetic field and magnetic storm affect flow of current in equatorial region. I have concentrated on how tidal oscillations and thermospheric wave related to current flow in equatorial region. Thermospheric wind have come into existence due to solar heating of the ionosphere solar wind have produced at higher latitude due to penetration of electric field. The hall current has produced due to magnetic field which also shows that how geomagnetic field affects conductivity.
