Self Cancellation of Higher Order Mode Spurious Frequencies in SIW Filters

, 2021
In this paper, a new approach for the suppression of higher order mode spurious frequencies in SIW filters is proposed. The proposed structure is a double layer SIW filter. In this structure, all couplings related to the higher order modes generating the

The effect of busbar structure on Q factor enhancement and spurious mode suppression in Lamb wave resonators

Applied Physics Letters
Lamb wave resonators (LWRs) exhibiting high-quality factors and clean spectra demonstrate promising applications in RF communication and sensing. This paper discusses the relationship between the spurious mode, the quality factor, and the effective ...

An Effective Approach to Suppressing the Spurious Mode in Rectangular Waveguide Filters

IEEE Microwave and Wireless Components Letters, 2019
In this letter, a new method for rectangular waveguides bandpass filters with improved stopband performance is presented. By setting the position of the coupling window, the coupling of the high-order mode can be attenuated, which makes it difficult to ...

Over 10% of ${k}_{\text{eff}}^{{2}}$ Demonstrated by 2-GHz Spurious Mode-Free Sc0.12Al0.88N Laterally Coupled Alternating Thickness Mode Resonators

IEEE Electron Device Letters, 2019
In this letter, a group of laterally coupled alternating thickness (LCAT) mode resonators based on 12% scandium-doped aluminum nitride (Sc0.12Al0.88N) are reported. The LCAT mode resonators are realized in-house by sandwiching a layer of 1- $ {\mu }\text{

Eradication of asymmetric spurious modes in AlN MEMS resonators using mode conversion

IEEE/LEOS International Conference on Optical MEMS, 2016
This papers reports on a spurious mode suppression technique that converts the asymmetrical (A0) mode to the intended symmetrical (S0) mode vibrations by installing a notch in aluminum nitride (AlN) laterally vibrating resonators.
