Problem 1 : (10 points) Consider a Teon-lled rectangular waveguide with inner dimension
Midterm Problem 2
(a)
Plug-and-chug!
(b)
Assuming only power flow in the direction and given the electromagnetic fields for the TE10
mode, the time average power flow is given by
Thus,
The time average power flow is given as . Notice that based on the way

Problem 1
This problem utilizes result from coupled line theory. Refer to the discussion of the even-odd
mode analysis of a length of coupled line in Section 7.6 Coupled Line Directional Couplers.
First, if we set , we ensure that the
