Since the work of Wu and Lee (1979) there has been renewed interest in the classical theory of electron cyclotron masers (Lee and Wu 1980, Lee et al. 1980, Wu et al. 1981, 1982, Hewitt et al. 1981, 1982, Melrose et al. 1982, Omidi and Gurnett 1982, Melrose and Dulk 1982). A useful idea in these recent developments of the classical theory concerns a geometric interpretation of the classical gyroresonance conditionwhere Oe, is the nonrelativistic gyrofrequency, s= 0, ± 1, ± 2,… is the harmonic number, is the Lorentz factor and ¦ and - denote components parallel and perpendicular to the magnetic field. In v-- v¦space (1) represents an ellipse with centre v¦= vc, v-= 0, eccentricity e0and semi-major axis Vparallel to the v-axis, with |
