Abstract :
The construction of diode oscillator with a field-emission cathode placed in a photonic crystal (PC) resonator is described. The PC resonator is composed by a 2D photonic-band-gap lattice of dielectric rods with a defect. Using 2D and 3D software packages, basic electrodynamic parameters of the PC resonator are calculated. Variation of the construction of the energy outputs allows adjustment of the loaded Q-factor in a wide range. Selection of optimal loaded Q-factor allows to maximize output power and efficiency for reasonable values of the cathode current density.
