A waveguide has a cutoff frequency for the TE 10 mode of 3 GHz.
(a) What is the cutoff frequency for the next higher mode
(b) Why is it desirable to use this waveguide above 3 GHz and below the frequency you found in part (a)
(c) A pulse of RF energy at a frequency of 5 GHz is sent down a 10 m length of this waveguide. How long does it take this pulse to get to the other end
(d) A designer wants to match a load to this waveguide. At a frequency of 5 GHz, what should the load impedance be
