Abstract
Selective launch, propagation, and absorption of right-hand (R) and left-hand (L) circularly polarized waves are investigated using an inhomogeneously magnetized plasma. When the R wave gets closer to the electron cyclotron resonance (ECR) point, the wave vanishes in the strong magnetic-field region before reaching the ECR point. On the other hand, the L wave, which has been considered not to be related to ECR, is clearly observed to be also absorbed near the ECR point. The former and latter phenomena are discussed in terms of the contribution of high-energy tail electrons and polarization reversal of the L wave to the R wave within the plasma, respectively.
