Determination of the Optimal Physical and Mathematical Model and Weight Functions for Calculating the Topology of Counterpine Converters of Surface Acoustic Waves

“…Більшість фізико-математичних моделей, що описують генерацію, поширення і детектування ПАХ базуються на представленні пристрою на ПАХ з ЗШП у вигляді трансверсального фільтра [1,[3][4][5][6][7].…”

Surface acoustic wave based microfluidic devices for biological applications

“…The change in SAWs velocity between the input and output IDTs will be characterized by the phase shift and amplitude difference, which are presented by an oscillating electric signal from output based on the piezoelectric effect. 32 It is also worth mentioning that SAWs have been used extensively in electronic communications such as cell phones for signal processing and filtering, 33 demonstrating that the devices of SAWs are highly compact, reliable, and low-priced, including the driving circuits and power supplies. Moreover, the power intensity of SAWs is proved to be safe for biological molecules and organisms, 34 ensuring that this technique has high biocompatibility.…”

Smart patterning for topological pumping of elastic surface waves

“…They are confined within a superficial region whose thickness is comparable with their wavelength (36). Manipulating surface waves has been of considerable interest with widespread applications in earthquake mitigation, nondestructive evaluation, wave filtering, and sensing (37)(38)(39). On the basis of the Bragg scattering and local resonance mechanisms, manipulation and control of surface waves have been recently investigated in the phononic and metamaterial community for various applications such as exotic wave transmission and reflection, wave focusing, and cloaking (40)(41)(42).…”
