What would be the attenuation per unit length be if the excitation frequency was 10 GHz
An attenuator can be made using a section of waveguide operating below cutoff, as shown in theaccompanying figure. If a = 2.286 cm and the operating frequency is 12 GHz, determine the requiredlength of the below-cutoff section of waveguide to achieve an attenuation of 100 dB between the inputand output guides. Ignore the effect of reflections at the step discontinuities.
