A rectangular air-filled waveguide WR510 used for cellular communication base stations has a cross-section of 5.1in×2.55in. (a) Calculate the cutoff wavelength λoc and the cutoff frequency fco for the dominant TE mode. (b) Determine the propagation constant and the transverse-wave impedance for this mode at f=10GHz. (c) How close are the values of (b) to the TEM values.
