  • Abstract
    This paper proposes a method for analysing the behaviour of transverse modes propagating under an SAW waveguide composed of IDT and weighted dummy electrodes. The proposed method can be used as one of the powerful tools to understand the behaviour of transverse mode propagation and to design wideband SAW resonators with suppressed spurious transverse mode resonances.
