“…Otherwise, the pulse emerging from the plasma is both compressed and frequency shifted. Pulse compression in plasma based on spatiotemporal variation of the plasma parameters and the resulting frequency chirping of the microwave pulse has been considered in the past [11]. Our approach is conceptually different in that it does not rely on frequency chirping or group velocity dispersion in the plasma.…”

A new approach to manipulating the duration and frequency of microwave pulses using magnetized plasmas is demonstrated. The plasma accomplishes two functions: (i) slowing down and spatially compressing the incident wave, and (ii) modifying the propagation properties (group velocity and frequency) of the wave in the plasma during a uniform in space adiabatic in time variation of the magnitude and/or direction of the magnetic field. The increase in the group velocity results in the shortening of the temporal pulse duration. Depending on the plasma parameters, the frequency of the outgoing compressed pulse can either change or remain unchanged. Such dynamic manipulation of radiation in plasma opens new avenues for manipulating high power microwave pulses.

“…Propagation of whistlers in plasma with time-varying magnetic field was examined by Kalluri (1996). Also it was theoretically proposed to use the strong whistler group velocity dispersion and the rapidly changing magnetic field to compress high-power microwave pulses in waveguides filled with magnetized plasma (Manheimer and Ripin, 1986). The experimental results concerning propagation of whistlers in time-varying magnetoplasma were reported by us previously (Kostrov et al, 2003).…”
