摘　　要：设计了一种中心频率为105GHz、带宽为10GHz的TE_(10)-TE_(11)-HE_(11)模式变换器,用于电子回旋共振波加热系统(ECRH)低功率测量平台的搭建,其中采用矩-圆过渡及渐变槽深波纹喇叭实现相关模式转换。仿真结果表明,频率范围为92~115GHz时,该模式转换器产生HE11模的转换效率即高斯含量达到95%以上。This article designs a TE_(10)-TE_(11)-HE_(11)mode converter with a central frequency of 105GHz and bandwidth 10GHz to build a low power measurement platform for the electron cyclotron resonance wave heating system(ECRH).Square-circle transition and gradient slot depth corrugated horn are used to achieve the related mode conversion.The simulation results show that the frequency range is 92~115GHz,the conversion efficiency of HE_(11)mode produced by this mode converter is higher than 95%with Gaussian content.
