"Stochastic Electron Acceleration in Obliquely Propagating Electromagnetic Waves" Physical Review Letters 58, no. 20 (18 May 1987): 2071–74. https://doi.org/10.1103/PhysRevLett.58.2071.https://doi.org/10.1103/PhysRevLett.58.2071http://hdl.handle.net/11603/39033Stochastic electron acceleration in intense electromagnetic waves, propagating obliquely to an ambient magnetic field, is considered. It is shown that when the waves' parallel phase velocities are supraluminous, the Hamiltonian surfaces are topologically open and, as a consequence, electrons can gain large energies. The results indicate that state-of-the-art, ground-based rf transmitters can accelerate ionospheric electrons to multimegaelectronvolt energies.4 pagesen-US©2025 American Physical Societyparallel phase velocitiesmultimegaelectronvolt energiesUMBC Optical Fiber Communications LaboratoryUMBC High Performance Computing Facility (HPCF)Stochastic electron accelerationtopologically openambient magnetic fieldHamiltonian surfacesintense electromagnetic wavesText
