Title: Theory and simulation of field emission diode oscillators

The results of a theoretical analysis of a diode oscillator with a field-emission cathode are presented. A small-signal analysis of self-excitation conditions is performed. The time-domain particle-in-cell code is developed, and the performance of an X-band oscillator is numerically demonstrated using the simulation code. The simulation shows a rather high output power and efficiency for reasonable values of cathode current density.
