An attenuator can be made using a section of waveguide operating below cutoff. Such a device consists of a waveguide of width a, followed by second section of the waveguide of width a/2 and finally with another section of width a If a 2.286 cm and the operating frequency is 12 GHz, determine the required length of the below-cutoff section of waveguide to achieve an attenuation of 100 dB between the input and output guides. Ignore the effect of reflections...
