Background, Motivation and Objective Surface transverse wave (STW) resonators on quartz provide excellent Q-factors and low loss in 2GHz frequency range [1].Meanwhile, the transverse modes were observed unusually situated on the left side from the main resonance, which was explained by concave form of the slowness curve in plane of substrate [2].Moreover, propagation along the busbars can, probably, radically change the acoustic field distribution across the aperture and introduce additional perturbation in 2-port resonator/filter performance [2].These effects can manifest themselves as notches and other perturbations of the narrow band 2-port resonator performance, which can be unacceptable for the device applications [3].In this presentation we analyze, using COMSOL simulations, the dependences of transverse modes on aperture, electrodes metal thickness and metallization and compare the results to experimental data.
