Microwave gyroscope-novel rotation sensor

High performance microwave gyroscope (MG) is theoretically developed for the first time to our knowledge. MG is based on Sagnac effect in microwave ring resonator (RR), where a specially tailored phase shifter (PS) on the basis of surface acoustic waves is inserted. Due to that the beat frequency becomes proportional to square (or cubic) root upon rotation rate, and therefore hugely increases. In the result MG has few order 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.
