An injection locked millimeter wave oscillator based on field emission cathodes

Abstract

We propose an injection-locked millimeter wave generator based on field emission mechanism according to the previous successful designs of the THz and millimeter wave devices. The design of this injection-locked device has been carried out and verified by the numerical simulations. A bandwidth of about 60 MHz has been obtained and it shows the consistency with the prediction of Adler's equation. The Q factor of the resonant structure is also calculated. An electronic efficiency up to 7% can be achieved without any external magnetic field applied.
