Zero temperature coefficient of delay for surface waves in quartz

This is the authors' abstract. We don't add key points for this paper.

Some new orientations and propagation directions possessing zero temperature coefficients of delay for surface waves in quartz with somewhat better electromechanical coupling than the ST cut are reported. One of the orientations also exhibits an almost-zero power flow angle. The results have been obtained using a nonlinearly based formalism in which the reference geometry, which remains fixed as the temperature is varied, may be employed.
