sorry,but i have this problem as an assignment>>it is very silly basic question about maxwell's equations but i don't know how to solve it
the question is:
use maxwell's equations to show that it is impossible for the TEM wave to exit with any single conductor wave guide (such as rectangular or circular wave guide)
HINT:for the integration over a closed loop of H.dl to have value in the transverse plane there must be alongitudinal flow of current (conductor or displacement)
note:in question it is written exit it may be exist i don't know!

yes it will not in any single conductor.it needs two conductor system to exists
( eg coax)
Yes, this is because no current will flow in only one conductor whether displacement or conduction.
