Abstract: The Universiry of Texas a t Austin It is well known that electromagnetic waves propagating along the magnetic field direction in the plasma are strongly absorbed when the wave frequency matches the electron cyclotron frequency. This absorption can be eliminated by adding a weak magnetic undulator that leads to the Undulator-Induced Transparency (UIT) of the plasma. Moreover, the group velocity of the waves in the plasma is strongly reduced, resulting in the extreme compression of the wave energy in the plasma…
