The frequency of a source wave is changed by a time-varying electromagnetic medium. A magnetoplasma is a suitable electromagnetic medium for frequency transformation since its dielectric constant can be changed by orders of magnitude by changing the plasma density or the direction and strength of the static magnetic fields. Two effects were described: frequency upshifting with power intensification of a whistle wave by a collapsing plasma medium; and conversion of a whistler wave into a controllable helical wiggler magnetic field. Moreover, by controlling the static magnetic field parameters and the level of ionization, the frequency shift ratio can be changed and the frequency transformer becomes tunable.
