Study of Ball Lightning Generated by Electromagnetic Wave Localization
Ball lightning that is a natural phenomenon behaves curiously and moves variously according to a huge amount of eyewitness reports. The ball lightning could be reproduced by an alternative experiment that was the result of a localized spherical plasma object (fireball) caused by microwave interference and discharge inside the cavity. In the experiment, the motion of the plasma fireball was exce...
متن کاملElectromagnetic Field Due to Lightning Strikes to Mountainous Ground
The produced electric and magnetic fields due to lightning strikes to mountainous ground are determined in this paper. For the sake of simplicity a cone-shaped ground with finite conductivity is assumed to represent a natural nonflat ground. By this assumption, we deal with an axillary symmetrical structure so we use the cylindrical 2D-FDTD to save the simulation memory and time, dramatically. ...
متن کاملTransform of Lightning Electromagnetic Pulses based on Laplace Wavelet
In this study, the fine structures of lightning electromagnetic pulse associated with 19 preliminary breakdown pulses, 37 stepped leaders, 8 dart leaders, 73 first and 52 subsequent return strokes were analyzed by using Laplace wavelet. The main characteristics of field waveforms such as, the correlation coefficient, the time of arrival and the dominant frequency of the initial peak field, the ...
متن کاملElectromagnetic pulses generated by meteoroid impacts on spacecraft
[1] Meteoroid impacts on spacecraft are known to cause mechanical damage, but their electrical effect on spacecraft systems are not well characterized. Several reported spacecraft anomalies are suggestive of an electrical failure associated with meteoroid impact. We present a theory to explain plasma production and subsequent electric fields occurring when a meteoroid strikes a spacecraft, ioni...
متن کاملInvertibility of current density from near-field electromagnetic data
The problem of determining a current density confined to a volume from measurements of the magnetic and electric fields it produces exterior to that volume is known to have nonunique solutions. Despite the nonuniqueness of the inversion we show that one may nevertheless uniquely determine certain moments of the vector spherical harmonic expansion of the current. It is demonstrated that the dete...
