1. A 1-cm X 3-cm rectangular air-filled waveguide operates in the TE12 mode at a frequency that is 20% higher than the cutoff frequency. Determine: (a) the operating frequency, (b) the phase and group velocities.
2. A microwave transmitter is connected by an air-filled waveguide of cross section 2.5 cm X 1 cm to an antenna. For transmission at 11 GHz, find the ratio of (a) the phase velocity to the medium velocity, and (b) the group velocity to the medium velocity.
