Andy,
The conservation of energy principle suggests that you cannot get more power
out of the lines than how much you put in. Assuming uniform, homogenious
coupled lines, this means the crosstalk voltage will be bounded by the
launched voltage(s) and reflections.
If a repetitive pattern hits a resonance (due to severe mismatches at both
ends), the voltage may escalate. A simple situation could be a more-or-less
matched agressor line coupling to an unterminated line (the matched agressor
is assumed only to avoid possible resonance gain on the aggressor itself).
If the frequency of active wavefront(s) on the agressor matches the
resonance frequency of the unterminated victim line, the crosstalk will be
bounded only by the losses.
Best regards,
Istvan Novak
