Development of a phase-lock system up to terahertz frequencies in microwave oscillators

The development of a phase-lock system up to the highest frequencies greater than one terahertz in microwave oscillators is considered. Applications of such systems for physical and technical measurements are discussed. Institute of Applied Physics of the Russian Academy of Sciences, Nizhny Novgorod, Russia.
