Question 1: Describe the operation of H-plane, E-plane and E-H plane Tee junctions. Why is a hybrid E-H phase Tee referred to as Magic Tee? Derive the scattering matrix for all of these Tees.
Question 2: Explain in detail the operation of a 2-hole directional coupler. Compute the coupling factor if the power in the primary waveguide is 72mW and the power delivered to the directional coupler is 8mW.
Question 3: Why are waveguide twists and bends constructed so that the direction of the propagated energy is gradually changed?
Question 4: Describe the functioning of flap and wave attenuators.
Question 5: What are waveguide joints? Illustrate their advantage and disadvantages.
Question 6: Describe the action of a rat-race junction.
Question 7: Write a note on waveguide Irises, Posts and Turning Screws.
