RT info:eu-repo/semantics/article T1 Geometry of fast magnetosonic rays, wavefronts and shock waves, Physics Letters A 380, 3817-3822 A1 Núñez Jiménez, Manuel AB Fast magnetosonic waves in a two-dimensional plasma are studied in the geometrical optics approximation. The geometry of rays and wavefronts influences decisively the formation and ulterior evolution of shock waves. It is shown that the curvature of the curve where rays start and the angle between rays and wavefronts are the main parameters governing a wide variety of possible outcomes.
