I am not sure what you think the "that" is. Are you perhaps confusing
multiple propagation modes for energy conversion between them? If you
are talking about a channel that has a discontinuity, then energy that
was propagating in one mode can convert to energy that propagates in
another mode past the discontinuity. We can measure the energy that
propagates in each mode. The modes are as real as anything else we see
with our instruments.
