Spatial localization of intense high-frequency fields in a plasma that is parametrically unstable in the lower hybrid resonance region
Gromov S.N., Pasechnik L.L., Semenyuk V.F.
Sharply localized intense radio-frequency (RF) fields were observed with the aid of a probing electron beam in a magnetized plasma during the nonlinear stage of the modulation instability of electron plasma waves with dispersion ω = a>pe(fcil / к). The characteristic amplitudes and the spatial scales of these fields, the appearance of which is attributed to collapse of plasma waves, are estimated.
