In the final analysis, by showing that 10 heterogenous clocks across three continents could agree with each other to within a ...

SummaryThis paper describes improvement of frequency measurement accuracy of fully digital phase detection QCM, which is a high-precision QCM. In fully digital phase (or frequency) measurement using ...

This paper presents an experimental study on the frequency stabilization of a terahertz resonant tunneling diode (RTD) oscillator by integrating the RTD with a high-Q photonic-crystal cavity. We ...
