Figure 1: The fraction of the input power, as a function of k z for k y = 0, that is reflected out on the
X-mode R X , on the O-mode R O , and mode converted to Bernstein waves: (a) for incoming X-mode
the conversion coefficient is C XB ; (b) for incoming O-mode the conversion coefficient is C OB .

Figure 2: The fraction of the outgoing EBW power, as a function of k z for k y = 0, that is converted to
the X-mode E X and on the O-mode E O . R B is the fraction of the emitted EBW power that is reflected
back into the plasma at the upper hybrid resonance.
