Abstract

Using the property of photonic band gap, we are able to design photonic crystal resonator in which a high order TM_mno mode can be stably supported and coupled to an external system without distortion of the high order resonance mode. The concept of this photonic crystal resonator with higher order mode is employed in X-band reflex klystron (PCRK) to demonstrate on experiment that the output power of PCRK is expected to be increased by m times n compared with that of conventional devices at the same operating frequency. Multiple electron beams with the beam voltage and current of 1kV, 100mA are used in PCRK using Spindt-type field emission cathode
