The surface acoustic wave (SAW) filter is widely applied in mobile communication, and the resonator its main component. However, traditional simulation design methods of resonators often require much computation because includes a multilayer structure many interfinger pairs. In order to improve efficiency designing, this paper proposed series neural network structural parameters backward based on performance indicators. We validate method using SAW 42°YX cut LiTaO3 substrate with an aluminum electrode. device consists interdigital transducer two reflector gates. test set results from data show that trained model has relative average error less than 5% devices' parameters, coefficient determination more significant 0.99. addition, we compare predicted experimental results, which excellent potential infer electrical response devices. provides solution for improving resonators.

Abstract Magnetic microparticles (MPs) and nanoparticles (NPs) have long been used as ideal miniaturized delivery detection platforms. Their use micro‐ nanorobots (MNRs) is also emerging in the recent years with help of more dedicated external magnetic field manipulations. In this review, we summarize research progress on nanoparticle (MNP)‐based MNRs. First, fabrication from either template‐assisted NP doping methods or directly synthesized MPs summarized. The driving torque sources for both types MNRs are analyzed, their propulsion control under low Reynolds number flows discussed by evaluating symmetry breaking mechanisms interparticle interactions. Subsequently, these scientific models, bioimaging agents, active delivery, treatment platforms (drug cell sterilization), biomedical diagnostics has reviewed. Finally, perspective MNPs‐based was outlined, including challenges future directions.
