2. (a) (2 pts.) Sketch the B vs o characteristic (phase constant vs angular frequency) of (i) a lossless strip line in air medium and (ii) an air-filled waveguide mode of a rectangular waveguide. BA (b) (2 pts.) Determine the range of dimensions a and b = % a of an air-filled rectangular waveguide a x b such that • the dominant mode has a cut-off frequency of fc 55 GHz . the next higher-order mode has a cut-off frequency of fc 26 GHz (C) (2 pts. How does your result in part b change if the waveguide is filled with a homogeneous dielectric medium having dielectric constant &r = 4?
