  • Abstract
    In this work, we study theoretically the operation of surface-acoustic wave (SAW) reflectors on the second harmonic frequency. There is a renewed interest in second harmonic reflectors for high-frequency devices and for sensor and tag applications. Here, we demonstrate that the reflectivity of the 2nd harmonic reflectors can be very high, e.g., on 128°-LiNbO3. We have simulated performances of a few typical SAW devices with such reflectors. Two times larger period of the structure makes it easy for production even in the frequency range from 2 to 3 GHz
