Relativistic-Amplitude electromagnetic waves – Beating the “magnetic” barrier Swadesh Mahajan, Research Professor, University of Texas at Austin Abstract: The dispersion characteristics of an arbitrary amplitude circularly polarized electromagnetic wave, propagating in a highly (thermally and kinematically) relativistic plasma, are shown to approach those of a linear wave in an unmagnetized, non-relativistic plasma. Further aided by high relativistic temperatures, the cut-off …
