Abstract:We suggest an approximation of the effect of the surface skimming bulk wave (SSBW) on harmonic admittance of periodic grating. The approximation is valid on both sides of cut-off frequency and predicts the existence of surface-bulk hybrid mode (SBH), if such mode occurs in the grating due to SAW/SSBW interaction. As an example, parameters of approximating function were calculated for 36°°°°X,Y+90°°°° cut of quartz with Al grating and plotted versus metalization ratio a/p. They revealed the existence of SBH mod… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
