Beam-tracing and profile evolution for localised beams in inhomogeneous plasmas
Lewin B. S. Marsh, Felix I. Parra, Valerian H. Hall-Chen +1
We derive the beam tracing and profile evolution for the propagation of any localised beam with arbitrary profile through an inhomogeneous cold plasma. We recover standard Gaussian…

Beam focusing and consequences for Doppler Backscattering measurements
Juan Ruiz Ruiz, Felix I. Parra, Valerian H. Hall-Chen +5
The phenomenon of beam focusing of microwaves in a plasma near a turning-point caustic is discussed in the context of the analytical solution to the Gaussian beam-tracing equations…
