A rectangular waveguide is to be constructed for single-mode operation at 3 GHz. The waveguide must be designed so that this operating frequency is 20% higher than the cutoff frequency of the lowest mode, and, at the same time, is 20% lower than the cutoff frequency of the next higher mode. The waveguide will be filled with a dielectric material with relative electrical permittivity of 2. Determine the cross-sectional dimensions, a and b, of the waveguide. Answer: 4.2 cm x...

1. It is desired to design a rectangular waveguide that propagates only the lowest order mode TE10 and operates at 10 GHz. If the waveguide is air filled, determine the waveguide dimensions (a and b) such that the desired operating frequency is 38% above the cutoff frequency of the TE10 mode. Although the dimension b of waveguide is often taken as b=a/2, for attenuation considerations and also to improve the waveguide power handling capacity, it is desired to design a...
