10 structure, wherein the generator and feed structure are capable of
11 delivering radio frequency (r.f.) power to the active and return
12 electrodes in lower and upper frequency ranges, the upper range
13 containing frequencies at least three times the frequencies of the lower
14 frequency range, and the generator and feed structure are arranged to
15 deliver r.f. power to the electrodes in the lower and upper frequency
16 ranges simultaneously.
