Available in PDF, EPUB and Kindle. Book excerpt: The technique of interaction of guided electromagnetic waves in magneto plasmas is utilized to study the phenomena resulting from the cylotron resonance (f = fH= gyrofrequency of electrons) absorption of microwave energy by the electron gas. The enhancement in electronic energy caused by this absorption is experimentally evidenced by study of (1) gyro-interaction of microwaves of different frequencies, (2) emission of microwave noise power at frequencies fn greater than fH, (3) intensity of visible light excitation and, (4) rapid disintergration of the plasma. A correlation of these experimental results show that (1) the rate of heating of any specific region of the plasma changes drastically during different time intervals of the pulsed resonant heating microwave sitnal and (2) non-uniform heating occurs along the plasma axis. Implication of these results on wave propagation in a magnetoplasma will be discussed. Electron cyclotron resonance abosrption of microwave energy by the electron gas in decaying magneto plasmas of oxygen and nitrogen gases is investigated. (Author).
