Consider a rectangular waveguide, with transverse dimensions a = 10.668 mm and b = 4.318 mm. The waveguide is uniformly filled with a non-magnetic dielectric with er = 2. We wish to use this waveguide to propagate a wave at frequency f = 13 GHz. (i) Which propagation modes can be sustained by this waveguide at 13 GHz? Explain in detail how you arrive at the answer. [10 marks] (ii) Calculate the propagation constant B for the allowed modes at f = 13 GHz. [4 marks] (iii) Assume that this waveguide is used to transmit digital data, by modulating the 13 GHz carrier wave. Calculate at what speed the information travels along this waveguide. Clearly explain the reasoning used to arrive at your answer. [6 marks]
