Chapter 11:
Frequency Shifts Induced by a Time-Varying Magnetoplasma Medium
Editor(s): Werner S. Weiglhofer; Akhlesh Lakhtakia
Author(s): Kalluri, Dikshitulu K.
An electromagnetic wave is transformed in a remarkable way by a time-varying magnetoplasma medium. The main effect of the temporal change in the parameters of the medium is the splitting of a source wave into new waves whose frequencies are different from the source wave frequency. Several problems involving either slow∕fast creation or slow∕fast collapse of the plasma medium in the presence of a static magnetic field are discussed. The more important results are (i) frequency upshifting with power intensification of a whistler wave by a collapsing plasma medium, and (ii) conversion of a whistler wave into a controllable helical wiggler magnetic field. A switched magnetoplasma medium can act like a frequency transformer.
