Abstract: | Characteristic features of the propagation of electromagnetic electron cyclotron waves in the vicinity of the electron cyclotron
resonance surface are investigated both analytically and numerically with allowance for variation in the magnetic field strength
and a corresponding variation in the magnetic field direction. It is demonstrated that variation in the magnetic field direction
can qualitatively change the wave propagation pattern and can markedly affect the efficiency of electron cyclotron resonance
plasma heating in an axisymmetric magnetic trap. |
