Abstract: Surface acoustic wave (SAW) technology is widely used in microwave electronics, and is often used to produce such devices as filters, sensors and actuators. In this work, a structure constructed by a two-dimensional phononic crystal (PnC) is designed to converge two incident SAWs. Based on the equifrequency contour (EFC) theory and unique band characteristic at high-symmetric point, aggregating SAWs within the PnC region and then the converged output could be observed. This specific utilization of PnC to converge SAWs can be a useful complement to the delicate manipulation, which can be highly desirable for developing SAWs device.
