Electromagnetic waves with frequencies above the extremely-low-frequency range (ELF; frequencies in the range 5 Hz-3KHz) are susceptible to a variety of solar proton event (SPE) effects when propagating through a polar region in the earth-ionosphere waveguide. These effects appear to become less sev...
