Simulation of whistler mode propagation for low latitude stations
Earth, Planets and Space volume 56, pages979–987(2004)
Representing lightning discharge current source by a Dirac delta function, Maxwell’s equations are solved to derive the expression for wave-electric field as a function of frequency and distance including the effect of interparticle collisions. The exact time-dependence of the propagating non-monochromatic signal for the realistic magnetospheric model is computed for low latitude stations (in India). The computation is extended for the wave propagating through different regions of the magnetosphere and results are compared with the measured data. Points of agreements and differences are illuminated.
