Question:

A rectangular brass (σc = 1.37 X 107 S/m) waveguide with dimensions α = 2.25 cm and b = 1.5 cm operates in the dominant mode at frequency 5 GHz. If the waveguide is filled with teflon (μr = 1, εr = 2.11, σ = 0), determine:

(a) The cutoff frequency for the dominant mode,

(b) The attenuation constant due to the loss in the guide walls.
