Jim, what happens to the ExB power density in the

Let's see E=0, and B=0; what power density, Cecil?

Play your silly word games if you will. Fields cannot
cancel unless those fields first exist. Assume E1xB1
joules/sec associated with the first field and E2xB2
joules/sec associated with the second field. The fields
cancel. What happens to the E1xB1 joules/sec and the
E2xB2 joules/sec? Hint: Their energy components are
redistributed in a direction that allows constructive
interference. In a transmission line, there is only
one other direction available.
