New method and its numerical application for whistler-mode propagation


O.Ferencz and P.Bognár

ABSTRACT

The whistlers are extremely useful for precising the physical model of the global atmosphere, monitoring the magnetosphere and expanding of our plasma-physical knowledge especially describing the distribution of particle densities in the high atmosphere. The papaer outlines the physical phenomenon itself, further reviews a computational procedure which delivers the exact time-space dependence of the propagating non-monochromatic signal directly from the Maxwell's equations. This new computational method gives an opportunity to calculate model whistlers using arbitrarily chosen excitational signals. The numerizing possibilities of the obtained formulas will be shortly set forth, then the calculated results for different models of media will be compared to the measured data. The comparision of the structure of measured and calculated whistlers for agreements and differences might produce a more realistic picture about the various properties of the plasma, the path of propagation and the signal oroginating.
