Evanescent modes in waveguides are non-propagating modes that decay exponentially with distance. For instance, in a waveguide with a TE11\text{TE}_{11}TE11 cutoff at 2 GHz, frequencies below this value (e.g., 1.5 GHz) generate evanescent modes. Mode Cutoff Frequencies for instance, a waveguide with a radius of 4 cm. The cutoff frequency for the TE11\text{TE}_{11}TE11 mode, the
