Application: TE/TM waves in strip lines. A parallel plate waveguide is made of two wide strips, separated by a fiberglass sheet d = 0.5 mm thick which has a relative permittivity of 3.5. Neglect any effects due to the edges of the strips (that is, assume the strips are infinitely wide) and calculate:

(a) The lowest TM mode possible.

(b) The lowest TE mode possible.

(c) If a wave at twice the lowest TE cutoff frequency propagates along the waveguide, calculate the wave impedance for the TE and

TM modes and compare with the wave impedance for TEM modes.
