Evolution of polarization in localized nonlinear Alfven waves
Journal Article

· Phys. Rev. Lett.; (United States)
A polarization change of localized and finite amplitude Alfven waves is found by use of both MHD theory and numerical simulation. One of the transverse components of the circularly polarized Alfven wave is stable as it propagates, but the other component is unstable under both self-focusing and diffraction effects. Consequently, the wave changes its polarization from circular to linear.
