Abstract
A study of one-dimension photonic crystal cylindrical cavity and metal cylindrical cavity has been finished under the help of ISFEL3D. The research shows that TM910 mode adjacent to TM010 only exists in the outermost layer mediator,it won’t interfere with TM010 mode. The frequency interval is 213 MHz. The characteristic impedance of one-dimensional photonic crystal cylindrical cavity(94.9Ω)is smaller than the metal cylindrical cavity’s(129Ω),but its uniformity is better. Besides,it has little effect on TM010 when the one-dimensional photonic crystal cylindrical cavity is connected to drift tubes. It means that one-dimensional photonic crystal cylindrical cavity has better ability to resist the disturbance of the drift tubes,which is the precondition of its application in high radio-frequency klystron.关键词
