The transmission of a high power electromagnetic (EM) waves from the HAARP facility in Alaska can excite stimulated electromagnetic emissions offset from the transmitter frequency near harmonics of ion cyclotron frequency. Stimulated ion Bernstein (SIB) occurs when the pump frequency is tuned to an electron Bernstein (EB) frequency near twice the electron gyro frequency. The SIB process is thought to involve mode conversion from EM to EB waves followed by parametric decay of the EB wave to multiple EB and IB waves. The production of SIB waves may be an indicator of strong cyclotron acceleration of electrons by the EB waves that lead to artificial aurora and impact ionization of neutrals.
