Conversion of a left-hand circularly polarized whistler wave into the magnetic energy of a controllable helical wiggler wave

Abstract

A linearly polarized electromagnetic source wave splits into six traveling wave modes (three of them are right-hand circularly-polarized (RCP) modes and three are left-hand circularly-polarized (LCP) modes) due to the interaction with a suddenly created magnetoplasma medium. When the angular frequency of the source wave is in the low-frequency region, the magnetoplasma supports two whistler wave modes (one is the transmitted RCP and the other is the reflected LCP). It is shown that the efficiency of energy conversion of the LCP whistler wave mode into the magnetic field of the wiggler is nearly of the same order of magnitude as the efficiency of the previously considered energy conversion of the RCP whistler wave mode.
