Third harmonic electromagnetic radiation observed in Interplanetary Type III radio bursts by
M. Reiner et al.*
Type III solar radio bursts, which appear as characteristic frequency-drifting features on radio dynamic spectra, are generated by energetic beams of electrons originating in solar active regions and propagating through the interplanetary medium. The remotely observed type III radiation consists of fundamental and harmonic components. Second harmonic electromagnetic radiation in type III solar radio bursts is well established at both high frequencies (metric and decametric wavelengths) and at low frequencies […]
