Abstract:
Solidly-Mounted Resonators (SMRs) are crucial in applications involving Radio Frequency (RF) and acoustic waves. Because they offer high-performance filtering and frequency control capabilities, the primary focus of this work is the design and simulation of SMRs using Barium Titanate (BaTiO₃) as the piezoelectric material. BaTiO₃ is a potential replacement for more conventional materials like ZnO and AlN because of its better electromechanical coupling and dielectric properties. The quality factor, frequency response, and acoustic wave propagation characteristics of the resonator are investigated in the study using Finite Element Modeling (FEM). A multi-layer acoustic Bragg reflector enhances acoustic wave confinement, lowers energy loss, and boosts device efficiency. The study also looks into how BaTiO₃-based SMRs are suitable for next-generation RF filters and sensing applications due to their improved resonance characteristics and higher coupling coefficients. The results offer a means to optimize SMR architectures for improved integration with modern sensing and communication technologies.
