Text: "Generation of a d.c. field by nonlinear electromagnetic waves in relativistic plasmas." A finite amplitude linearly polarized electromagnetic wave propagating in a relativistic plasma, is found to generate the longitudinal d.c. as well as the oscillating electric field at the second harmonic. In a plasma consisting of only electrons and positrons, these fields cannot be generated. However, electrostatic scalar potential alone can render a situation relativistic. Also, the author finds that most of the pulsars emit coherent radio waves in the range (100-600) Mhz with a cut-off near 1 Ghz.. The emissions are frequently linearly polarized.. Astrophysics and Space Science. 79(1), Sept. 1981. p. 25-36.
