Abstract
In this paper, we calculated the mode-coupling characteristics of multi-stepped bi-mesa resonators and compared them with beveled resonators. Calculation results showed that increasing the number of mesa steps reduced coupling between the thickness-shear and thickness-flexure modes. These results indicate that the multi-stepped bi-mesa resonator has a good mode-decoupling effect, and its performance characteristics approach those of the beveled resonator.
