Field-emission based vacuum devices for the generation of THz waves
ABSTRACT A vacuum electronic device based on field emission mechanism for the generation or amplification of THz waves is proposed. The field emission electrons are bunching and synchronizing with THz wave through well-tailored metallic structures. Two types of interacting structures are considered. One is double-sided coupled cavity and the other is single-sided coupled cavity. The electric field patterns of the corresponding resonant modes of each circuit model is presented.
Conference Proceeding: An injection locked millimeter wave oscillator based on field emission cathodes[show abstract] [hide abstract]
ABSTRACT: The frequency range of the millimeter wave is from 30 up to 300 GHz. Millimeter waves have been extensively studied for many applications including high resolution radars, communications, materials processing, plasma heating, high energy particle accelerators and power transmission. In this paper, an injection-locked millimeter wave oscillator based on field-emission cathodes is proposed and demonstrated the well phase/frequency controllability. The simulation results are consistent with the prediction of Adler's equation. The preliminary results show that the design of the injection-locked oscillator seems to promise useful and compact millimeter wave sources.Vacuum Nanoelectronics Conference, 2007. IVNC.
