Power relations in integrated strip lines. In a strip line, the strips are separated a distance 0.02 mm and the strips are 1 mm wide. The material between the strips is air and because the width is much larger than the separation, the edge effects may be neglected. Calculate:
(a) The total time averaged power that can be propagated in the lowest TE mode at a frequency 25% above cutoff.
(b) The total time-averaged power that can be propagated in the lowest TM mode at a frequency 25% above cutoff.
(c) Compare the results in (a) and (b) with the power propagated in the TEM mode at the same corresponding frequencies.
