Abstract

The advantages of using photonic bandgap (PBG) structures in vacuum electron devices and transmission lines are discussed. Excellent mode selectivity in PBG structures permits them to be employed as overmoded interaction structures in microwave tubes for either high power (>10 MW) or extremely high frequency (>100 GHz) operation. A 140 GHz highly overmoded gyrotron oscillator has been experimentally demonstrated. The theoretical study of PBG structures for high power microwave devices has been carried out. These theoretical results have been used to design a gyrotron device interaction circuit and a 90 GHz, oversized, highly mode-selective PBG waveguide.
