AB: Electromagnetic radiation at the plasma frequency and/or its second harmonic, the so-called plasma emission, is widely accepted as the fundamental process responsible for solar type II and type III radio bursts. The traditional theory based upon weak turbulence three-wave and nonlinear wave-particle interaction processes predicts radiation emission primarily at the fundamental and second harmonic of the plasma frequency. This paper presents the first demonstration of third and higher harmonic plasma emission on the basis of two- dimensional electromagnetic particle-in-cell simulation experiment. This finding indicates that under certain circumstances, fundamental-harmonic pair emission might also be accompanied by the third- and/or higher- harmonic component(s), a result that may be highly relevant to certain observations.
