Microwave gyroscope - Novel rotation sensor

high-performance microwave gyroscope (MG) is theoretically developed for the first time to our knowledge. The MG is based on the Sagnac effect in a microwave ring resonator, where a specially tailored phase shifter, (PS) on the basis of surface acoustic waves is inserted. In the result, the MG has a few orders higher sensitivity and dynamic range than state-of-the-art laser gyros, so it can serve as an advanced rotation sensor in navigation and fundamental sciences.
