No spurious second harmonic mode can be found in the frequency band of 14 to 26 GHz in the results of both simulation and measurement.
When the second mode coupling occurs, the second harmonic mode will appear in the frequency band in which the power in the [TE.
It can be observed that the second harmonic mode is excited both in the measurement setup and in the computer simulation, and can be predicted accurately if an appropriate electromagnetic model is used.
To suppress the spurious second harmonic mode one can use asymmetric filter structures and maximize the attenuation band with intensive optimization, or use ridged waveguide filters, in which the second harmonic mode cannot propagate through the filter.
Hidden spurious harmonic modes in corrugated waveguide filters are investigated from both theoretical and practical points of view.
Having understood the mechanism of the hidden spurious harmonic modes, the following simulation scheme can be proposed to predict the spurious modes.
