Coherent interaction between charged particles and an elliptically polarized electromagnetic wave propagating across a static magnetic field B. is investigatedanalytically and numerically. The particle can be unlimitedly accelerated along thewave front on a plane across the field B.. The trapping condition is obtained thatdepends on the polarization angle 0 of the wave, the ratio E. / B. and the phase veloc-ity F. where E. is the magnitude of the electric field of the wave. Once an L-polarizedwave with 0 is found to satisfy the condition, an R-polarized wave with 7[ -0automatically satisfies it provided E. / B. and F. are common to the both cases. Somefeatures of an extraordinary wave which is a plausible candidate of the driving wavesin a magnetized plasma are also discussed.
