摘　　要：为了有效利用谐振腔的高次模式,使之在毫米波回旋管等器件中发挥重要作用,该文使用一种新型复合开放式谐振腔结构。通过合理设置内腔壁和耦合孔尺寸,提高了腔中谐振模式的选择性。利用Ansoft HFSS高频分析设计软件,对这种腔中模式的谐振进行了数值模拟计算。结果表明这种新复合式谐振腔结构能够有效抑制竞争模式。A new complex open-cavity structure is used for improving the mode selectivity of gyrotron resonator by means of setting a right rational position of the common wall and the shape of coupling slots between the inter- and outercavities. The characteristics of the resonant modes in the cavity are simulated and analyzed with Ansoft HFSS code. It is shown that mode competition can be effectively suppressed with the new cavity structure.
