question

Consider an air-filled rectangular waveguide whoseaandb dimensionsare 0.9 and 0.4 in., respectively. Find (a)thecutoff frequency of the dominant mode and also that ofthe next higher-order mode, and (b)theattenuation factor associated with the next higher-ordermode at a frequency midway between the two cutofffrequencies.
