WebExample: Circular Waveguide Design Design an air‐filled circular waveguide such that only the dominant mode will propagate over a bandwidth of 10 GHz. Solution: the cutoff frequency of the TE 11 mode is the lower bound of the bandwidth. The next mode is the TM 01 with cutoff frequency: 01 2.4049 cTM 2 c f a WebSolutions to the radially inhomogeneous infinite circular waveguides have been obtained numerically from an exact theoretical development beginning with first principles. These inhomogeneous waveguides are layered with circular, concentric annuli, possibly having complex constitutive parameters.
